theres a lot of things that can throw you off, like stupid things, but that doesn't mean it's not real. mine had a T-Type horn insert, but the numbers matched on everything.
some GN's had chrome grilles depending on year, check the interior, if it's grey with the turbo6, most likely it is, i don't think anyone would go through the trouble of taking a regal and putting in GN interior. also check for the 3.8L SFI TURBO badge on the hood, and the ehxaust, also the wheels play into it too, they're all automatics, GNX's have a badge on the dashboard with a number on it, also when the hood is up look at the 'hood blanket' for the BUICK turbo6 on it, and also the turbo shroud. if it's a v8 or some crap it's not. also, it's intercooled. very very very few T-types were intercooled also.
like i said if u dont know what your looking for you can be easily fooled
i thought mine was a GNX from about 20 ft away until i walked up to it and saw it wasn't. fun cars, pita on certain things, and that motor cannot be killed.
