Well, currently we only have 5 at our house. But that number should go up yet again very soon. We currently have:
1990 Grand Prix STE 4 Door McLaren/ASC 3.1L Intercooled Turbo
1990 Grand Prix 2 Door McLaren/ASC 3.1L Intercooled Turbo
1993 Grand Prix LE 4 door, 3.1L
2002 Grand Prix GTP 4 Door 40th Anniversary, Supercharged 3.8L
and the 2000 Bonneville, Supercharged 3.8L
I am working on getting a '92 GP STE with the 3.4L DOHC engine.
