after doing some research over the internet on trying to how much a classic mustang can go for. I thought I would ask y'all. My dad and I want to go to an auction and bid on some cars. Does anyone know how much a 66-69 fastback mustang goes for at auction? I looking for a 289 or bigger block with a manual transmission. I would prefer not to get a mint condition one, because I do want to a few things to it. BUT I do not want a junkyard car.
