2006 Pontiac Grand Prix GT 4dr Sedan (3.8L 6cyl S/C 4A)
I love what they have done with the 2006 model. If you get a chance to get the leather interior I would highly suggest it for max comfort. The back seat room is totally fine and the sun roof does not crowd the head space. I am 6 foot 2 and can sit in it with much ease. (Also have a wife and a 19 month daughter that are able to sit very comfortably as well. If you are looking for a stealth design with some need for speed while still being able to up hold some class, the GT version is the way to go hands down without breaking your pockets.
Sunroof, Xm radio, leather interior, bright and easy to read gage, 17" wheel package.
Making the On star completly optional instead of mandatory built in. NOt the pontiac fault just GM in general.
