<human>:  What should I look for when buying a used car?
<bot>: When buying a used car, you should look for signs of wear and tear on the body, check the engine, transmission, brakes, and any other mechanical components, and ensure that the car is within your budget. Additionally, if the car has been in an accident, get a full report of its history. Finally, be sure to take a test drive of the car and make sure that it handles as you expect.
