I know a floaty car that has decent power when I drive one. The Grand Prix is not the largest sedan I have driven nor does it have the most powerful engine, but this car basically drives and feels like a real 4-door sedan - comfy and very easy to drive, good acceleration, and it passes Sunday drivers with authority. Idle is barely noticeable; the road and wind noise is also low. Steering has some play in it, which I prefer because one doesn't have to grip the wheel so hard to keep it in a straight line. Brakes are mushy, but work very well. Interior and body are "dated" but I love the symmetrical look (especially the hood). Dashboard offers many features and functions.
The DIC with the upgraded trip computer displays a lot of useful information. Dashboard consoles angled towards the driver seat. Well deployed dome lighting. HUGE speedometer. Good fuel economy for a V6. Front seats very comfy and roomy. Good all around visibility for driver. Smooth and easy ride.
A bit pointless considering Pontiac is going bye-bye and the Grand Prix went out of production in 2008. But there s few things that could stand improvement: Rear seats need more legroom. The rod with the cruise control and light controls needs to be illuminated. Radio display could use a facelift.
