They will tell everyone your car is overpriced even if it is priced $1k less than a dealer. Dealers are heavily favored on this websites and I'm sure Cargurus is getting kickbacks from the dealers. A car is a car, it really doesn't matter who you buy it from. Most of the dealers out there are dirty and crazy some of the stuff I have been subjected to over the years. My car is under full factory warranty, but Cargurus doesn't even ask about a warranty if you are a private party. My car is in amazing shape and should still command a hefty price, as I paid one. Cargurus is very confusing and lies to the customers about real time vehicle pricing. I would rather buy a car from a private party, than try and trust a dirty dealer!
