Car Ownership Money Traps: 12 Ways Your Vehicle Could Be Costing You More

Your car requires plenty of money for gas, insurance, maintenance and repairs. But some of the costs of car ownership are avoidable. See if any of these car money traps are making your vehicle more expensive than it needs to be.

Owning a car is expensive even when you’re doing everything right.

There’s gas. Insurance. Registration. Tires. Maintenance. Repairs.

Then there are the expenses we sometimes create ourselves.

We postpone a small repair until it becomes a bigger one. We keep renewing the same insurance policy without checking the price. We choose a car based on the monthly payment rather than what it will ultimately cost.

Or we burn through extra gas simply because we’re making three trips we could have combined into one.

Some car costs are unavoidable. But you can often take steps to avoid the following money traps.

Money Trap #1: Driving on Improperly Inflated Tires

When did you last check your tire pressure?

Underinflated tires can reduce fuel economy and contribute to uneven or premature tire wear. Improper inflation can also affect handling and safety.

Don’t automatically inflate tires to the pressure printed on the tire itself. Use the vehicle manufacturer’s recommended pressure, usually found on a label inside the driver’s door or in the owner’s manual.

And don’t rely solely on your tire-pressure warning light. Periodically checking with an inexpensive tire gauge can alert you to a problem before the pressure drops enough to trigger a warning.

The money trap: Paying for additional fuel and potentially shortening the useful life of expensive tires.

Money Trap #2: Making More Car Trips Than Necessary

A quick run to the grocery store doesn’t feel particularly expensive.

Neither does tomorrow’s trip to the pharmacy.

Or the trip back to the grocery store because you forgot something.

But every unnecessary trip puts more miles on your vehicle.

And every mile has costs beyond gasoline. You’re also using tires, oil and other vehicle components as you move your car closer to its next maintenance interval.

Combine errands when practical. Keep a running shopping list. Before making a special trip for one forgotten item, see if you can substitute something you already have or wait until you’re going that direction anyway.

The money trap: Looking only at the gasoline used for an extra trip rather than the total cost of putting more miles on your car.

Money Trap #3: Putting Off Preventive Maintenance

Skipping maintenance saves money today.

Unfortunately, your car doesn’t necessarily forget that you skipped it.

Follow the maintenance schedule for your particular vehicle rather than relying on a generic list of what a car “should” need at a particular mileage.

That includes oil changes and other manufacturer-recommended maintenance.

A trustworthy mechanic can also help you distinguish between something your vehicle actually needs and an additional service someone is simply trying to sell you.

The money trap: Saving a relatively small amount on maintenance only to risk a much larger repair later.

Money Trap #4: Ignoring Small Problems and Warning Lights

A strange sound starts.

The car develops a slight vibration.

A warning light appears.

It’s tempting to think, I’ll deal with it if it gets worse.

Sometimes nothing serious is wrong. Other times, continuing to drive can turn a manageable repair into a much more expensive one.

A check engine light can indicate many different problems, so the light itself doesn’t tell you what needs to be repaired. Some auto parts stores will read diagnostic trouble codes at no charge, but remember that a code identifies where the vehicle detected a problem. It doesn’t necessarily provide a complete diagnosis or tell you which part to replace.

And a flashing check engine light or a warning involving oil pressure, overheating, brakes or another potentially serious condition deserves prompt attention. Follow your owner’s manual, and don’t continue driving a vehicle that may be unsafe or damaged.

The money trap: Hoping a problem will go away while the potential repair bill keeps growing.

Money Trap #5: Paying Someone for Every Simple Car Task

There are plenty of auto repairs that should be left to someone with the proper skills and equipment.

Changing windshield wipers probably isn’t one of them.

Depending on your vehicle and abilities, you may also be able to replace certain bulbs, cabin air filters or engine air filters yourself.

Before paying shop labor for a simple maintenance task, check the owner’s manual to see whether it’s something you can safely and comfortably handle.

But don’t attempt a repair simply because a video makes it look easy. A botched DIY job can cost considerably more than paying someone to do it correctly the first time.

The money trap: Paying labor charges for easy jobs you could safely do yourself — or attempting difficult jobs you shouldn’t.

Money Trap #6: Using More Expensive Fuel Than Your Car Requires

Premium sounds better.

That doesn’t mean it’s better for a vehicle designed to run on regular gasoline.

Use the fuel grade recommended by your vehicle manufacturer. Generally, buying a higher octane than your vehicle needs isn’t a money-saving maintenance strategy.

On the other hand, if your manufacturer requires premium fuel, don’t downgrade simply to save a few dollars.

The money trap: Paying extra at every fill-up for something your particular vehicle doesn’t need.

Money Trap #7: Driving in Ways That Waste Gas and Wear Out the Car

How you drive affects more than your fuel bill.

Rapid acceleration, hard braking, speeding and aggressive driving can increase fuel consumption and put additional wear on tires and brakes.

Following too closely also means you may need to brake harder when traffic slows (in addition to increasing your accident risk).

Leave enough time to get where you’re going and enough space between you and the vehicle ahead.

A calmer drive can be easier on both you and your car.

The money trap: Spending more on fuel and wear while potentially increasing the risk of an extremely expensive accident.

Money Trap #8: Never Shopping Your Auto Insurance

Staying with an insurer you like has value.

Paying significantly more than necessary for comparable coverage doesn’t.

Insurance rates can change for many reasons, so periodically compare your current premium with quotes for comparable coverage elsewhere.

The important word is comparable.

A cheaper policy isn’t a bargain if you’re getting substantially less protection, accepting a deductible you couldn’t comfortably cover or dropping coverage you actually need.

Ask about discounts, too. Your driving habits, annual mileage, vehicle use or other circumstances may have changed since you bought the policy.

The money trap: Automatically renewing year after year without knowing whether your rate is still competitive.

Money Trap #9: Cutting Insurance Coverage Just To Lower the Premium

The opposite insurance mistake can be far more expensive.

Don’t select coverage solely by asking, “How low can I get this monthly bill?”

Learn what each coverage actually protects, and consider what you could afford to pay yourself after an accident.

An insurance agent or broker can help explain your options if you’re unsure.

Higher deductibles can reduce premiums, for example, but only make financial sense if you could actually come up with the deductible when needed. (See Raising Your Deductible Can Lower Your Auto Insurance Bill—But Should You?)

The money trap: Saving a little every month while exposing yourself to a financial loss you couldn’t absorb.

Money Trap #10: Shopping for a Car by Monthly Payment

This may be one of the biggest car-buying traps.

A salesperson or lender can make an expensive vehicle look more affordable by stretching payments over a longer period.

But a smaller monthly payment doesn’t make the car cheaper.

Longer financing can mean paying more interest and remaining in debt longer. It can also increase the amount of time you owe more than the vehicle is worth.

Instead of asking only, “Can I afford this payment?”, look at:

The vehicle’s purchase price
Your down payment
Interest rate
Loan term
Total interest
Total amount you’ll repay

Also consider whether GAP coverage is appropriate when financing. Understand what it covers, what it costs and whether you may already have access to it through an insurer or lender.

The money trap: Using a long loan term to squeeze an otherwise unaffordable car into your monthly budget.

Money Trap #11: Buying More Car Than You Need

The purchase price is only the beginning.

A larger, more expensive or more powerful vehicle may also mean higher insurance premiums, more expensive tires, greater fuel consumption, higher financing costs and more expensive repairs or replacement parts.

Even depreciation deserves consideration. A large portion of the cost of owning some vehicles comes from the value they lose while you own them.

Before buying, look beyond whether you can afford to get the car off the lot.

Ask what it is likely to cost you to keep it on the road for the next several years.

The money trap: Focusing on the purchase price while overlooking the ongoing costs of owning the vehicle.

Money Trap #12: Having No Plan for Car Repairs

Eventually, something on your car will need to be repaired.

That isn’t really an emergency in the sense that it’s unexpected that a car will ever break. What’s unexpected is what will break and when.

If every $600 repair has to be put on a high-interest credit card, the repair ultimately costs more than $600.

When possible, build an auto repair category into your savings.

Even $25 or $50 per month gives you something to work with when the battery dies, a tire needs replacing or the mechanic delivers unwelcome news.

If your car is older, you may want to gradually increase the amount you keep available for repairs.

The money trap: Budgeting for gas and insurance but forgetting that repairs are part of the cost of owning a car.

Know Your Car’s Four Numbers

You don’t need to become an automotive expert to control car costs. Start by knowing four numbers:

Recommended tire pressure: Find it on the vehicle information label or in your owner’s manual.
Maintenance schedule: Know what your manufacturer recommends and approximately when major maintenance is coming.
Current insurance premium: Know what you’re paying so you can meaningfully compare quotes.
Monthly car savings: Know how much you’re setting aside for repairs, tires and eventually replacement.

Keeping track of those four numbers can help prevent several of the money traps above.

Budget Level Savings: Where To Start Cutting Car Costs

No need to tackle every tip at once. Start with the tips best suited for your budget.

If money is stretched and savings need to be meaningful:

Start with things that cost nothing or very little.

Consolidate trips. Check tire pressure. Stop unnecessary aggressive driving. Review your insurance. Learn which basic maintenance tasks you can safely perform yourself.

Most importantly, don’t ignore a developing problem simply because you can’t comfortably afford the repair. Find out what’s wrong first. Waiting may reduce your options rather than improve them.

If you’re cutting back but still have some flexibility:

Begin setting aside something each month for repairs and future tires, even if the amount is small.

Keep up with manufacturer-recommended maintenance and periodically compare insurance rates.

If you have a car loan, consider whether extra principal payments make sense after accounting for your other financial priorities and loan terms.

If you just want small, easy wins:

Think beyond keeping today’s car running.

Start saving toward your next vehicle before you need one. The larger the amount you can eventually put down — or potentially pay in cash — the less dependent you’ll be on whatever financing terms are available when replacement day arrives.

TDS Takeaway: Your Cheapest Car May Be the One You Already Own

There’s one final car money trap worth mentioning because it doesn’t fit neatly into the list.

Getting tired of your car isn’t the same thing as needing another one.

A repair estimate of $1,500 can make replacing an older vehicle seem like the obvious choice. But compare that repair with the total cost of replacement, not with the value of your current car.

A newer vehicle could bring a monthly payment, higher insurance premiums, taxes and registration costs, along with depreciation.

Of course, there comes a point when an unreliable or unsafe vehicle isn’t worth continuing to repair.

But don’t assume that putting $1,500 into a $5,000 car is automatically foolish. If that repair gives you another reliable year or two without car payments, the numbers may favor fixing what you already own.

The cheapest car is often the reliable one that’s already sitting in your driveway.

Before You Replace an Older Car

A big repair bill can make a new car look very appealing. Before making the decision, compare:

Cost to repair your current vehicle
Other major repairs likely to be needed soon
Current vehicle reliability and safety
Replacement vehicle purchase price
Financing costs
Difference in insurance premiums
Taxes, registration and other purchase costs
Expected fuel and maintenance costs

Don’t ask only, “Is this car worth spending $2,000 on?”

Also ask, “What will replacing it cost me?”

Those are two very different questions.
