i bought this car not knowing to much about but the guy i bought it fomr says it is pretty rare it is 1989 trans am gta with a 350 tpi stock and a 700r trans it also has a 327 9 bolt rear end with disc brakes (he says that is the rare part) it is white with grey interior and t tops. thanks for your help

 

its not rare as the 9 bolt was very avail on the upper end models. my 89 formula has the 9 bolt with 3.45 gears but those came in stick cars and the autos got the 2.77, 3.27 and 3.08 rears. yes there is a 3.08 9 bolt but itr shares only the ratio of the 10 bolt counterpart. they arent interchangable.

i will say the 89 is a 1 year car if ya wanna consider that rare. it was the last year for MAF, first year for PBR brakes last year for the 9 bolt although i have heard some 90 models getting them as GM depleated thir stock of 9 bolts and first year for over the shoulder rear seat belts and first year fo no 9th injector.

 

1989 was technically the only year in the US you could have gotten a GTA with the L98 (350) AND the CC1 (T-tops). There are some earlier (1987 & 1988) Canadian bound GTA's that I have seen with the combo, but no US versions.

If you want rare, make that car a convertible, which would make it one of 140, or more rare a FORMULA 350 Convertible, then you can honestly claim "Rare"
