First, it may not be a GTP. I thought it was in 04 that they dropped the GTP and the supercharged GP's were just GT's. Im not sure what year that happened in though. I have seen some 04 looking GP's that have GTP Supercharged in a smaller badge on the rear on the right side of the trunk lid.
Also, they switched from the VIN codes of 1 and K for the 3800 (1 Being the L67) to VIN codes of 2 and 4 and I havent a clue as to which one is the L32 power plant.
I dont see anything on the rear trunk lid that would indicate to me it has the badge but it is a VIN Code 4 engine if that will help you.
Any of you out there that have an '04 supercharged GP that can report what the 8th character/number is in their VIN?
I believe it was actually 06 they started the supercharged gt thing, because 05 still had the gtp badging.
My 04 comp-g vins 8th charecter is the number 4
