It looks like the conditions could improve for buying a used car in 2025. Consumers may not be able to exert the buying power of 2019–before COVID and the pandemic shutdown strangled supply and sent prices soaring–but conditions are more in the buyer’s favor. Over the course of 2024, used car prices were volatile, but have overall trended lower.The average price of a used car was $25,000 in March 2025. Some of those cars will need to be financed, and higher interest rates present their own challenge. Another thing to watch out for is a drop in the quality of trade-ins. Some of these problems are not obvious. It’s never been more important to get the best possible vehicle for your money. Here’s what to look for when buying a used car.

When Buying a Used Car, the Questions Matter

This is not the time for shyness. Bring a friend with you to make sure you stick with your questions. These 12 will help you make a decision.

1. Why Are They Selling the Car?

Listen carefully to the answer and let the prospective seller talk as long as possible. Within the explanation could be important clues as to why they’re offloading this vehicle besides a desire for a new set of wheels.

2. What Is the Value of The Car By the Book? 

Don’t rely on the car owner for this answer. You need independent information to help with negotiating. Go to websites like Kelley Blue Book to get a range of value for the car. This is also a prime opportunity to ask how they arrived at the asking price.

3. What Is the Mileage?

Everyone knows that years cause automobile wear and tear. Americans drive an average of 14,263 miles a year, according to the Federal Highway Administration. Do the multiplication. Does the number they give you make sense considering how old the car is?Recommended: Financing a Used Car with Over 100K Miles

4. How Many Owners Has the Car Had?

Is the car’s current owner the first one? If not, does the seller know how many people have owned it previously? How long has the seller owned the vehicle? If someone is trying to sell a car after owning it for a year or even less time, there might be some big problems.

5. Do They Have the Title in Hand? 

A longtime owner might not be sure of the location of the title. The problem is, a seller might not have the title because there’s an outstanding loan from the bank. A clear title is free of any doubts about the ownership of the vehicle. If the seller has it, you can be certain that someone won't appear to try to take back the vehicle after you've paid for it.Recommended: What to Do if You Lost Your Car Title

6. Do They Have Service/Maintenance Records?

 If the seller doesn't have records of maintenance for the car, all is not lost. You might be able to obtain the records from an authorized dealer for the vehicle's make. The bottom line: Cars need regular tune-ups and oil changes. If a vehicle hasn't been maintained regularly, it could mean you will end up with costly repairs.Recommended: Guide to Car Depreciation

7. Has the Car Been in Any Accidents?

A dented bumper isn’t a tragedy. But if the car has been in a big accident and needed bodywork or even a new engine, you really need to know that. The repairs might have left lingering problems. 

8. Is the Vehicle Under Warranty? 

A private seller may possibly not know this. But a dealership will certainly have access to warranty status. If a car is still covered, it could save you money. If you’re working with a dealer, you may be able to buy an extended warranty.

9. Has the Car Ever Been in a Flood?

If the car has been exposed to flooding, it could cause problems with the electrical system. Look out for mold and rust, too. To find out if there is rest, you may need to look at the car’s underbody with a flashlight.

10. How Would the Purchase Affect Your Car Insurance Premiums?

Your insurance premiums may go up with this purchase. Insurers look at the age of the car as well as make and model. Get in touch with an independent insurance agent before you close the deal to hear the numbers.

11. Can You Take the Car for a Test Drive? 

Being able to sit in the car and drive it is crucial. A test drive is the only way to find out how the car handles. Plus it will reveal any issues the seller may not be aware of (or is hiding). If a seller refuses to allow a test drive, that's a bad sign.

12. Can You Take the Car to a Mechanic for an Independent Inspection? 

You should only ask this if you’re serious about buying a used car. But if you are, then you should ask–and if you get any pushback, that, too, is a bad sign.Recommended: What Happens to a Car Loan When Someone Dies

The Takeaway

And it’s essential you listen closely to the answers and proceed with prudence in making your decision.Sometimes you need a car loan to afford a vehicle, used or new.
