I purchased a vehicle 10 months ago in "clean" condition with two previous owners (according to the GM of a dealership that I purchased it from, it was his personal vehicle). After 2k in repairs I returned to the dealership and asked them to evaluate my trade. They offered me 13,500 (wholesale) when I paid 25k for the car. They offered me no explanation. Another dealer pulled the Auto check and told me there were two mileage flags for rollbacks and eight previous owners. Are dealerships required to disclose auto check odometer flags and rollbacks? After speaking to the manager I know they also use the autocheck system. The gm was terminated a month after I bought the car for "shady" practices, but the dealer insists the car was in excellent condition (even though they won't offer even low trade value to take it back).
