2006 Pontiac Grand Prix GT 4dr Sedan (3.8L 6cyl S/C 4A)
Fun drive! I had a 2000 Grand Prix GT that I loved & traded in at 70,000 mi. The 200HP non supercharged got 20 city- 29 HWY mpg.The '06 260 HP/SC gets 10 city- 24 Hwy,"overall lousy mpg." Dealer cannot get rid of rattles in rear door panel and sunroof.Anyway, I should have kept the 2000.
