Saving Money When Buying a New or Used Car

Saving big on a vehicle isn’t just about haggling a few hundred dollars at the dealership. The smarter decisions happen earlier—what you buy, how you buy it, and how you pay for it.

#1. Consider a Certified Pre-Owned (CPO) Program

A CPO (certified pre-owned) vehicle can give you almost-new quality for thousands less than a brand-new version of the same model. If the current design has been around for a few years, a 2–3-year-old model will often have the same platform and features as the newest one, but at a big discount.

Unlike random used cars, CPO vehicles usually include inspection, reconditioning, and a factory-backed warranty. Many brands (Lexus, Kia, Honda, Ford, Nissan, Hyundai, Chevrolet, etc.) also include perks like free roadside assistance and trial satellite radio. If you’re trying to save money, a recent CPO model almost always makes more sense than buying brand new.

#2. Sell Your Car Yourself (Not to the Dealership)

Dealership trade-ins are convenient—but usually costly. You’ll almost always get more by selling privately to an individual than trading in at the dealer. Expect a few hundred to a few thousand dollars in extra value if you’re patient and present the car well.

Use Autotrader, Craigslist, Facebook Marketplace, or local classifieds. Clean the car thoroughly, fix obvious issues, and price it realistically. The extra effort can significantly reduce what you need to finance on your next car.

#3. Think Mid-Level, Not Fully Loaded

Top-of-the-line trims cost thousands more than base models on most model lines — check the manufacturer’s own price sheet for the car you’re looking at. Ask yourself whether the extra gadgets are really worth thousands of dollars. Often, a mid-level trim gives you the features you actually use without the premium price tag.

#4. Buy from Dealer Stock

Dealers are more flexible on vehicles already sitting on the lot than on special orders. If you’re open to colors and options already in inventory—possibly at nearby or regional dealers—you can often negotiate a better price.

#5. Read the Fine Print (Especially on Financing & F&I)

Finance & Insurance (F&I) is where a lot of dealer profit hides—extended warranties, add-ons, and marked-up loans. Listen to offers, but have your own financing lined up in advance through a bank or credit union. Always read the fine print on warranties, loans, and “extras.” If you don’t understand a fee, ask for it to be removed.

#6. Negotiate Online

You must visit in person to test drive a car, but you can negotiate price and even finalize paperwork remotely. Many internet sales departments are volume-based, not commission-based, which can mean better pricing.

By negotiating online, you also bypass some of the high-pressure tactics in the showroom and can compare offers on your own schedule.

#7. Make Dealers Compete

Once you know the exact make and model (and options) you want, email multiple dealers and ask for their best out-the-door price. Make it clear you’re contacting several dealerships and will buy from the lowest bidder.

Be very specific so quotes are truly comparable. Then, pick the best price—or use the lowest quote to negotiate with other dealers.

#8. Bring Your Own Financing

BYOF (bring your own financing) is simple and powerful. Get preapproved at a bank or credit union before visiting the dealership. It gives you clear budget limits and leverage—if the dealer can’t beat your rate, you already have a solid option.

#9. Negotiate the Car Price First

Keep each part of the deal separate: price, trade-in, financing, and incentives. Start with the car price only. Once you lock that in, then talk about trade-in value, rebates, and financing. This prevents the dealer from “giving” you money in one area and taking it back in another.

#10. Remember: Everything Is Negotiable

Preprinted fees and add-ons are not sacred. Documentation fees, dealer add-ons, and extras can often be reduced or removed. If a fee looks suspicious or excessive, challenge it—or ask the dealer to offset it by discounting the car.

Saving Money on Car Maintenance

Modern cars need less frequent service than older ones, but maintenance still adds up. Smart maintenance can save you money now and prevent expensive repairs later.

#1. Use Regular Fuel (When Permitted)

If your owner’s manual says premium is “recommended” rather than “required,” you can often safely use regular. Most modern engines have knock sensors to adjust timing and prevent engine damage. You might lose a bit of power or efficiency, but the savings at the pump usually outweigh it.

Exception: If your manual clearly states premium is required (especially for turbo/supercharged engines), follow that guidance.

#2. Don’t Change Oil Too Often

The old “every 3,000 miles” rule is outdated. Follow your owner’s manual or the vehicle’s oil-life monitor instead. Over-changing oil wastes money without providing extra protection. Just make sure you don’t go longer than recommended.

#3. Build a Relationship with a Trustworthy Mechanic

Jumping from shop to shop often costs more in the long run. Find a local, reputable mechanic and give them consistent business. When you become a loyal customer, you’re more likely to get honest advice, better pricing, and occasional discounts.

#4. Consider Warehouse Clubs for Tires

Stores like Sam’s Club and Costco often offer competitive tire prices and include services like rotations, balancing, and flat repair in the installation fee. Always compare total package costs, not just the tire price.

#5. Don’t Ignore the Oil Light

If an oil pressure warning light comes on, pull over and shut off the engine as soon as it’s safe. Continuing to drive can destroy the engine. Check the owner’s manual and, if necessary, call for a tow.

#6. Follow Preventive Maintenance

Regular, manufacturer-recommended maintenance is cheaper than major unexpected repairs. Use small jobs (like oil changes) to “test” a shop’s honesty and quality before trusting them with bigger work.

#7. Know What Your Vehicle Actually Needs

The owner’s manual is your best friend. A dealership might recommend frequent flushes and services that aren’t required. Transmission service is the usual flashpoint, and the interval is set by your manufacturer, not by a rule of thumb: plenty of CVTs and dual-clutch boxes want attention far earlier than the long intervals you’ll hear quoted. Look it up in the manual and quote it back.

#8. Do Simple Repairs Yourself

Basic tasks—like replacing wipers, some bulbs, and cabin air filters—are surprisingly easy with online tutorials. Doing simple jobs yourself can save a lot on labor over the life of your car.

Saving Money on Car Repair

Repairs are often unexpected and stressful, but you can control some of the cost.

#1. Find a Shop You Trust and Stick With It

Build a relationship with a shop that is AAA-approved, ASE certified, and well-reviewed online. Ask friends, check Reddit, and local Facebook groups. Once you’re confident in their honesty, give them repeat business.

#2. Avoid Unnecessary Maintenance

Don’t blindly accept every recommendation. Compare suggested services with your owner’s manual. If a shop gives you a long list of “urgent” items, ask what truly can’t wait, then verify with a car-savvy friend.

#3. Purchase Your Own Parts (Selective)

Some parts may be cheaper from reputable online retailers or parts stores. If your mechanic is willing to install customer-supplied parts, you can save on markup. Only do this when you’re confident you’re buying the right part.

#4. Consider Tech Schools or Side Work Carefully

Auto tech schools may offer discounted services performed by students under professional supervision. You can also sometimes hire mechanics for side work. Both can save money—but use judgment and make sure you’re comfortable with the arrangement.

Saving Money on Gas

Fuel costs add up quickly, but small changes in how, when, and where you drive can make a big difference.

#1. Use Apps and Discount Programs

Use gas price apps to find the cheapest stations nearby and avoid overpriced “convenience” stations. Consider discounted gift cards and gas rewards programs through grocery chains and warehouse clubs.

#2. Maintain Tires and Filters

Correct tire pressure is the one with real numbers behind it. The Department of Energy and EPA put the gain at about 0.6% on average, up to 3% from keeping tires at the proper pressure, and the loss at roughly 0.2% for every 1 psi you are low across all four tires. Modest, but the safety and tire-life case is strong on its own, so check pressures monthly.

The air filter is a different story, and it’s worth correcting a tip you’ll see repeated everywhere. On any car with a fuel-injected, computer-controlled engine — which is essentially every car on the road — the Department of Energy says replacing a clogged air filter does not improve fuel economy, though it can improve acceleration. The fuel saving applies only to older carbureted engines, and even there it’s a few percent. Replace the filter because the engine needs clean air, not to save gas.

#3. Lighten Your Load

Two separate effects here, often muddled together. Extra weight costs fuel through mass: the Department of Energy puts an extra 100 pounds at roughly 1% of your MPG. A roof box costs fuel through drag, and that one is big — around 2% to 8% in city driving, 6% to 17% on the highway, and 10% to 25% at 65 to 75 mph. So clear out the trunk, but take the roof box off the moment you’re done with it.

#4. Drive Smoothly and Obey Speed Limits

Aggressive driving wastes fuel and raises your accident risk. The Department of Energy and EPA measure the fuel cost of speeding, rapid acceleration and hard braking at roughly 15% to 30% at highway speeds and 10% to 40% in stop-and-go traffic. Gas mileage drops off quickly above 50 mph: every 5 mph over that is, in their words, like paying an extra 21 cents a gallon. Idling burns a quarter to a half gallon an hour depending on engine size and air conditioning. Driving smoothly saves real money and keeps you safer.

#5. Combine Trips and Plan Routes

Short, individual trips on a cold engine burn more fuel than combining errands into one outing. Use apps like Waze to avoid congestion, construction, and unnecessary idling.

#6. Carpool and Commute Smarter

Carpooling reduces fuel usage, wear and tear, and often lets you use HOV lanes. Smarter commuting—using your most efficient car, avoiding rush hour when possible, and sharing rides—can lower both gas and insurance costs.

Save Money by Driving Less or Carpooling

Carpooling isn’t just for kids. Adults can benefit hugely from shared rides—especially for commuting.

Commuter Carpooling

Commuter carpooling lets you split gas, parking, and tolls while reducing your time in traffic (thanks to HOV lanes in many areas). You also reduce vehicle wear and tear and your annual mileage, which can lower insurance premiums.

The Benefits of Carpooling

#1. Save Money on Gas, Tolls & Parking

Sharing rides means sharing fuel, tolls, and parking costs. Over a year, this can add up to hundreds of dollars in savings per person.

#2. Increased Safety & Less Stress

Fewer cars on the road means fewer chances for accidents. Longer trips are safer when you’re not alone, and you can share driving duties on road trips.

#3. Environmental Benefits

Carpooling reduces emissions and helps ease congestion. If you care about air quality and the environment, it’s a simple way to help.

#4. Social Benefits

Carpooling can turn an isolating commute into social time with coworkers or friends. If you use apps or online services, you don’t even need to know riders beforehand.

Saving Money on Car Insurance

Insurance is often one of the biggest ongoing car costs—but it’s also one of the easiest to optimize. Many drivers overpay simply because they never review their policies.

#1. Shop Around

Rates vary dramatically between insurers. At renewal, get quotes from at least a few well-reviewed companies. The spread between the cheapest and most expensive quote for the same driver and the same coverage is routinely large, which is the whole reason to re-shop rather than auto-renew. How much you personally save is not something anyone can tell you in advance, so get the quotes.

#2. Drop Collision on Old Cars

Once your car’s value drops below a few thousand dollars, collision coverage often isn’t worth the cost. Dropping it removes one of several coverages from your premium, so the saving is real but it is not most of your bill. Ask your insurer to quote the policy with and without it and compare the two numbers against what your car is actually worth.

#3. Bundle Policies

Insuring your home and auto (or renters and auto) with one company can unlock multi-policy (multi-line) discounts. Bundling discounts vary a lot by company, so get the bundled and unbundled numbers from each carrier rather than assuming a standard rate.

#4. Consider Usage-Based Insurance (UBI)

Many insurers offer telematics programs that track your driving habits and can reward safe, low-mileage drivers with discounts. If you drive gently and mostly during the day, UBI can save serious money. If you frequently drive late at night or brake hard, it may offer less benefit.

#5. Ask About Mileage Discounts

If you drive much less than the average (especially under 10,000 miles per year), ask for a low-mileage discount. This is especially valuable for retirees, remote workers, and students living on campus.

#6. Maintain a Strong Credit Score

Where state law allows it, insurers use credit-based insurance scores, and good credit can lower your auto premium while poor or no credit can raise it. California and Michigan keep it out of personal auto rating by statute: California’s auto rates turn on three mandatory factors and credit is not among them, and Michigan’s rating law lists credit score among the factors an insurer may not use. Per the NAIC’s own survey of state rules, Hawaii and Massachusetts also bar it, and several more states restrict it — Maryland on new business only, Oregon and Washington barring cancellation or non-renewal on credit, Utah allowing credit only to reduce a rate. The NAIC also notes that in most states an insurer cannot use the score as the sole reason to raise your rate or to deny, cancel or non-renew you. If you’re in one of those states, paying bills on time is still worth doing — just not for this reason.

#7. Delay Teen Drivers (When Practical)

Adding a teen driver is usually the single largest premium increase a household sees, and how large depends on your state, your carrier and the teen’s age. If possible, delay licensing until they’re older, or have them contribute toward their own insurance. Also, compare the cost of putting them on your policy versus a separate one.

#8. Use Good Student Discounts

Good grades can save 6–20% for teen and college drivers. Many insurers reward students with a GPA of 3.0 or higher.

#9. Skip Small Claims

Filing a claim for minor damage can raise your premium for years. If the cost is close to your deductible and there’s no injury or third-party damage, consider paying out of pocket to keep your record clean.

#10. Buy a Car That’s Cheap to Insure

Sports cars and luxury models are expensive to insure. For lower premiums, choose vehicles with good safety ratings, low theft rates, and modest repair costs.

#11. Take Advantage of Safety & Other Discounts

Ask about discounts for:

Anti-theft devices and alarms
Anti-lock brakes and airbags
Marriage or long-term residency
Good driving record and defensive driving courses
Memberships, employers, or professional groups

#12. Raise Your Deductibles (If You Can Afford It)

Higher deductibles on collision and comprehensive mean lower premiums. Moving from a $500 deductible to $1,000 is the common step, and $1,000 is no longer unusual: J.D. Power’s 2025 claims research found 26% of customers carried $1,000 or more. How much it saves depends on your carrier and your state, so ask for the quote both ways — and only take the higher deductible if you could actually pay it after a claim.

#13. Carpool and Audit Your Driving Habits

Insurers rate you partially on how much you drive. Carpooling, biking, or using public transit can reduce your annual mileage and may qualify you for low-mileage discounts. If you’ve recently changed jobs or moved closer to work, let your insurer know—many people forget and overpay.

FAQ on Saving Money on Your Driving Expenses

What’s the single biggest way to save money on car expenses?

For most people, the biggest savings come from how they buy and insure their cars. Choosing a slightly used CPO vehicle and shopping around for cheaper insurance can easily save thousands over the life of the car.

Is buying a certified pre-owned car really cheaper than buying new?

Yes. A CPO car that’s 2–3 years old often has the same features and styling as the current model but costs thousands less, and it usually includes inspection, reconditioning, and a factory-backed warranty.

How often should I change my oil to save money without damaging my car?

Follow your owner’s manual or oil-life monitor—not the old 3,000-mile rule. Modern engines and synthetic oils usually allow much longer intervals, which saves money without sacrificing protection.

Are older cars always cheaper to own?

Not always. Older cars can be cheaper to insure and don’t need full coverage, but they may require more repair and maintenance. The key is balancing lower payments and insurance with realistic repair costs.

How much can I really save by shopping around for car insurance?

Many drivers save a few hundred dollars a year by switching insurers with the same coverage. Rates vary widely between companies, so getting multiple quotes at renewal is one of the easiest wins.

Is carpooling actually worth the hassle?

Yes. Carpooling can cut your fuel costs, reduce wear and tear, lower annual mileage for potential insurance discounts, and save time if you can use HOV lanes. Even once or twice a week makes a difference.

Where should I start if I feel overwhelmed by all these tips?

Start with the highest-impact areas: shop your insurance, check your maintenance habits, and improve fuel efficiency with smoother driving and better route planning. You can add more strategies over time.
