2007 Pontiac Grand Prix GT 4dr Sedan (3.8L 6cyl S/C 4A)
This is my 2nd Grand Prix. I was hoping for the same overall performance and economy as my 2002 but it didn't happen. The fuel mileage is nowhere near 27, 18 is the highest to date. The transmission is sloppy from 1st to 2nd in traffic, the dealer says its "hunting" to save fuel. Then it does find the gear it slams hard. It is very unpredictable. On the plus side the interior is great, car is very power full and fun to drive and it looks great.
Supercharged engine,Dual climate control, trip computer, remote start, heated seats. The dash layout is perfect.
Fuel mileage, Add auto dimming rear view mirror, and a method to lock the trunk.
