That, in turn, would give the horsepower crown to the 2005-2008 Pontiac Grand Prix GXP, a front-wheel-drive sedan backed by a 5.3-liter V8 that's good for 303 ponies.

I traded in 2 Saturns for a black 2008 Grand Prix GXP with 62,300 miles. I've gone though it with new coils, wires, plugs, wipers, filters, some fluids changed and a new set of tires.
