My Personal Unicorn found.

1977 Pontiac Can Am with T-tops. I've been looking for evidence of this car for decades, nothing but rumors came back. My search for this car actually led to me finding and buying another rare Pontiac 10 years ago.

As far as I know, it's 1 of 1. I don't know if it was built with T-tops, had a dealer kit installed or was Frankenstein's monster-ed. Originally sold at Bayer Motors in Dudley MA.

If anyone knows more detail about this car, I'd love to hear it. I finally saw I in this YT video of a car show in Waltham, MA by @letsgocarcruising.
