Human: How do I know if the new car I'm considering buying has been in a wreck? Assistant: 
You can ask the seller to provide you with a Carfax report, which is a vehicle history report that provides information about any previous accidents or damage. Additionally, you can look up the vehicle’s Vehicle Identification Number (VIN) on sites like Carfax and AutoCheck, both of which will give you access to the vehicle's full history.
