Nice find

And it is also a special feeling when you have been after it for so long. I understand your sleepless night.
Over here those cars were called "Pizzaracers", in the seventies all the pizzeria owners had one. That led to that nobody else wanted them at that time. The pizzeria owners quickly learned that it was no good idea to show of like that. Since they made a lot of black money it was easy for the authorities to track them down through the cars. And that made it even worse to have one TransAm for those that was working honestly
Time has changed and it is no problem to own a "Pizzaracer" here today, even if the nickname lives on...
BTW, it looks like it just need a good cleaning and polishing.
