Let's see some pictures of Notchbacks! There probably aren't too many since there were only 625 made in two years (1988, 1989)!

According to PMD, the photo of the Notchback TTA was a prototype Pace Car that Pontiac fitted with the rear decklid to gauge support for or against using the Notchback on the TTAs in '89.
From what I understand, it was a consideration in order to make the cars more distinctive and less like a "usual" GTA. I personally think it would have been a great idea; the exposure it gained would have no doubt increased sales and awareness of the AA8 option.
But it was already canceled by the time the '89 production got under way.

Sorry about the BS flag. They made one notchback in 1989. The rest were all made in 1988.

Hey, GTAJIM, do you have a digital dash cluster too?

Yeah, mine's digital. Somebody stole my emblems. I meant to buy new ones, but I have other stuff to get first (like brakes & tires!). The previous owner let the car sit outside for 3 years without driving it. So needless to say, I've been busy trying to fix it. I have had it for 3 years now and it is 100% better than when I received it (It wasn't even running then & it had a rats nest, fun stuff!).
