I have not seen but 1 manual mbm trans ams before out of around 15 total. Mine in an auto with tan interior. They pop up every now and then on autotrader. I had found a formula that was ok but the bumper was cracked, it was a 6 speed hardtop car with the hardtop the same color as the car. It has to have been sold by now. I use Searchtempest to check out craigslist for stuff like that but I still end up finding everything on autotrader. They didn't make the mbm cars in a ws6 or an SS wasn't sure if you knew that or not.
Here is a link to the production number breakdown if you have not seen it. https://ls1tech.com/forums/pontiac-f...l#post12704374
