I'm thinking about buying a new car, but I'm worried about buying a lemon. How can I tell if the car I'm thinking of buying is a lemon?

You should check for any signs of damage or rust on the exterior and inside of the car. Check the oil levels and make sure they are within the manufacturer's specifications. Test drive the car to get an idea of its performance. If you're still unsure, take it to a mechanic to have it checked out.
