what is your warranty on used cars?

First off Cargurus is just a listing site for sellers and dealers. You will need to contact the seller for specifics, such as warranty. Deliver is contracted using an auto shipper of your choosing and costs are paid by you. Once you buy a vehicle in almost all cases, it is yours and returning a used car is very hard, especially a used car. I suggest you deal with only vehicles sold by dealers like Carvana. With them, you can purchase a vehicle and it will be delivered to your house, all costs included and you have a week to return if you don't like it. You can also buy local to avoid all of this.

CG's does not sell or warranty cars.
