I just bought one really nice shape 85,000 miles. I'm slowly gathering this n that not too much out there. The cheapest way would be a junker for parts in a junk yard, or high mileage beater. Those parts individually will be costly. Floor mats, supercharger hood emblems no longer available at any GM dealer.GTP 40 Emblems are still available dealer wants $70.00 each plus tax, I have found them for $50.00 nos.at several websites like Gm giant parts,o e parts I think was the other. I really love this car, good luck on yours.
