2007 Pontiac Grand Prix GT 4dr Sedan (3.8L 6cyl S/C 4A)
This is a powerful and fun car to drive. It handles well and goes like Jet Stink when you need it. Primary complaint is that at Highway speeds, it gets 22.5 - 24.5 maximum, no where near the 28 EPA estimate. I can usually meet or exceed the highway EPA estimates in all my vehicles, but not this one. The 3.8 V-6 normally aspirated gets 30 - 34 on the highway, but lacks the power. Interior is a little tight and design is dated. I was sorry to see the Bonneville retired, but this is a close substitute. Runs fine on regular gas. I expect excellent reliability on the proven 3.8 V-6 and 4 Speed Automatic. AC works well as usually for GM.
