2006 Pontiac Grand Prix GXP 4dr Sedan (5.3L 8cyl 4A)
My GXP has been perfect, no problems at all. Really is fun to drive and I love the purr of the V-8 motor. I trade cars every 2 to 3 years, but this is a keeper. I even bought an extended warranty for 7years and 84,000 miles. Told my wife to bury me in it. Mileage is not great, but a 400+ mile trip last year netted about 24MPG and not at 55MPH either.
