Wow, that is sad. I had no idea of how expensive it was, or how few GTs were left.
It is. And frustrating. He also had to ship them a set as if they were a customer so they could approve the experience a customer has receiving the parts. As if there is something special about getting parts from GM.
My math on the GTs is an estimate: The Fiero Store used to pull registration records from all fifty states annually, until the cost went way up. The last time they did this, between 5 and 10 years ago they found about 10% of the original 370,000 still registered. Total fastback GT (the 85 GT was a notchback) production was 40,619. 10% of that, less some loss over the last few years is about 4000. An argument can be made that they are preferred so more are around, and that there are some that are not registered. But at the same time, there's no chance that a set of these will be sold for every remaining fastback GT.
I hope it all works out for the person paying and doing the work on this. I'll buy a set for eval, and maybe a second depending on how they look. GM sure isn't winning over any fans with their greedy behavior, though.
