Does Car Gurus have any guarantee for return on a car purchases

Cargurus doesn't buy or sell anything. It's an advertising site only. Similar to Craigslist, Facebook Marketplace, etc. You'll need to talk to the selling Dealer about this. I can tell you that shipping costs and arrangements are the responsibility of you, the buyer. Some Dealers will help you with the shipping arrangements. Look for a little truck icon on their ad. Hope that helps! Jim

One other thing, you should always have the vehicle inspected BEFORE you buy it so you know what you're buying! I've used lemonsquad.com for my long distance purchases with excellent results. Jim
