7 questions to ask when buying a used car

Many buyers think Lemon Laws, or a cooling-off period, will automatically apply and get them out of a sticky situation when buying a used car that turns out to be misrepresented or just plain awful. Each state's particular laws are different, but before getting yourself into a mess trying to return a terrible car to a reluctant dealer, you should ask about the things discussed below.

We spoke with Sergei Lemberg, a New York-based lawyer specializing in Lemon Laws, and he provided the following essential questions one should always ask a seller. Some of these apply to dealer sales only, but they are still great examples of how thorough you should be in grilling someone selling a car.

Questions to ask when buying a used car in 2024:

1. Do you have the repair history for this vehicle?

"If the car is relatively new, or Certified Pre-Owned," Lemberg says, "a manufacturer's dealership should be able to look up the Vehicle Identification Number (VIN) and provide you with a record of the work that's been done on the car at various dealerships. While it won't include repairs by shops that aren't affiliated with the manufacturer, you could glean important information about problems encountered by the previous owner."

We'll also note that, when buying a used car, you can ask a dealer for a CarFax to learn more about a particular car's history and find any potential red flags.

2. Where is the Buyer's Guide?

"Federal law says that every used vehicle must have a Buyer's Guide conspicuously posted, typically on one of the rear windows," says Lemberg. "The Buyer's Guide will let you know if the dealer is selling the car 'as is' or if there is a warranty. If there's a warranty, the Buyer's Guide will let you know what's covered and how much the dealer will contribute for repair costs. If no Buyer's Guide is posted, turn around and go to another dealer."

3. What is your return policy?

Lemberg says it's a myth that the law mandates a cooling-off period, during which time you can return a vehicle if you change your mind. Nevertheless, some dealers have a return policy when buying a used car. "Find out what the return policy is," he says, "And get the policy in writing. Some states also have lemon laws for used cars, but it's an option of last resort."
