<human>:  I'm going to buy a used car. What should I look for and ask the seller?
<bot>: When considering a used car, it is important to ask the seller what work, if any, has been done to it recently, the vehicle's history and any service records, the number of previous owners, and any ongoing maintenance needs. Other essential details to look for when purchasing a used car include checking for rust, worn tires, exterior and interior damage or other signs of wear, as well as taking a look at the suspension and steering systems and inspecting the engine. To keep yourself safe, you should also ask to test drive the car and look into any available warranty options.
