Wow! - That is like maybe $10M or more in valuation for (4) cars?.
Reading thru my old Pontiac Mags, I came across another blog on the (8) cars, and the VIN's were listed. At that time of the article writing (1980's), one of the (8) was unaccounted for.
But I found this blog attached on the "Pontiac Trans Am Forum".
The 8th car was found, and had spent a good deal of time in salvage yards, and was in bad shape. It seems it was found somewhere around 2014/2015, restored, and made its debut at the 2016 MCACN.
A great read!
