Recently, I traded a 2001 911 to enter the BMW family. In the process of shopping for a decent trade-in, I met up with multiple dealers who offered me super low quotes based on "wholesaler pricing." Then a buddy told me he was able to make a deal for an M5 based on finding out the "wholesale" price and offering more than that. He said his car was 2 years old, had 20k, and listed over $90k. He negotiated a deal for $55k. I guess I am just naive. Is it common practice to find the "wholesale price" when buying a used car? I have been looking at Cars.com, NADA, KBB, Edmunds, E-bay... where does one go for a real wholesale price ... other than by trying to trade a car in?
