2006 Pontiac Grand Prix GT 4dr Sedan (3.8L 6cyl S/C 4A)
I really like driving this car. There is a GM service bulletin for the transmission. I average 30 on freeway trips and have averaged 23 in town. But if I use the boost, oh how it drinks the fuel while I smile from the power. No lag like a turbo either.
Angled toward driver dash, supercharger, dual zone climate, traction control, quiet highway ride, sportier than Chevy/Buick suspension.
