My father has enlisted me to sell his 1979 Year One custom build Burt Reynolds edition Trans Am. Information about the car can be found here:

They start at $130,000 and easily reach $200,000 all optioned out. This one is one of the early Prototype cars and doesn't meet any of the BanI BanII, BanIII criteria, but lies somewhere between a BanI and BanII. It was given away to a contest winner on a television series documenting the build. My father purchased it through auction from the contest winner. Currently there is a waiting list to get one of these, despite the astounding price.

Currently it is sitting at a custom shop while the hood is sent back to Year One to be properly re-done. The cowl intake was out of whack and my dad slammed the hood down on it. Costly mistake, but in a few weeks it will be a mint car again with only 1500 miles on it since the build.
He is wanting $79,000 for it, which I think is reasonable considering the staggering cost Year One wants for one of these. Being a Prototype TV giveaway car gives it an extra bonus as well.
While I have a lot of car sales experience, I have never attempted to sell any classic vehicle with this kind of price tag. I was hoping some people on this forum with experience can point me as to where to list that will yield buyers. Obviously I can't slap it on craigslist.

I'm looking into Hemmings, Autotrader classics, TA forums and other web sites specializing in TA sales. I might even give Ebay a shot.

Hopefully there's some experience here with selling high end niche cars.
