Human: What are some of the most important things to keep in mind when buying a used car? Assistant: 

1. Make sure you have a good idea of what kind of car you're looking for and research it thoroughly before going to look at any potential vehicles.
2. Ask questions about the vehicle, such as how many miles it has on the odometer and whether there have been any accidents or repairs.
3. Inspect the exterior and interior of the car, including checking the engine and brakes.
4. Test drive the car to get an idea of its performance and handling.
5. Get a CarFax report to make sure the car is free from major issues and has no hidden problems.
6. Consider getting an independent inspection done by a trusted mechanic.
7. Negotiate the price if necessary.
