2006 Pontiac Grand Prix GXP 4dr Sedan (5.3L 8cyl 4A)
I drove a G6 and loved the tight body. The GXP is not as tight, but the V8 power is awesome. I disagree with Edmunds because they aren't factoring in price and gas mileage. The Charger may be a better car, but it's a new model. Grand Prix has been around a few years. Also, the Charger, which is much heavier doesn't get 28 mpg on the highway (GXP does if you use cruise control). Also, I got a loaded GXP for 28000. A similarly equipped Charger would go for 35000, and OnStar isn't even available! In an other 18 months, I am going to get the G6 GXP!!
V8 Power. Awesome seats. Great trunk space. Cool rotors and aluminum wheels.
