I have a mate with a black Boss 429 that has been deemed the most original Boss 9 in the world, with 7034 original miles and he has been offered triple what most go for, for it. He declined. Impressive will power there! Better man than I!!
I'm probably not going to go down a concours path with my black one, but rather run a 5 speed, and a Holman Moody original Boss 9 Nascar engine in it for fun. Do the car mostly stock, but the power plant to drive and enjoy.
