2005 Pontiac Grand Prix GTP 4dr Sedan (3.8L 6cyl S/C 4A)
From the day I bought the Grand Prix GTP I really enjoyed the performance of the supercharged engine. The only problem is the low roof line. I enjoy driving long distances the seats and gauges are excellent. Gas mileage is okay for a large midsize car. Even though the 3.8 is old technology, GM has come a long way with making the engine quite yet with the supercharger it is very responsive.
The outside design and the interior layout are excellent.
Find a way to raise the roofline. The rest of the car is excellent.
