<human>:  What do I need to know when buying a used car?
<bot>: Some important things to consider when buying a used car are: the car's overall condition and reliability, the mileage, the cost of any repairs needed, and any potential safety issues. It is important to also get a vehicle history report, research consumer reviews, and check for any open recalls on the car. Additionally, you should always test drive the car and get an independent inspection.
