GXP = WOW
By James on
2006 Pontiac Grand Prix GXP 4dr Sedan (5.3L 8cyl 4A)
I went into to drive and buy a G6 GTP and drove off with a GXP. The hiway mileage is great...My first measured tank got 25 mpg...with a 300 hp V8! It is incredibly quick....be ready for a real jolt when you put the pedal down. I got the employee discount. A lot of people notice and ask quesions about it.
V8 power V6 economy. Great seats.
more standard pinstriping. otherwise it's a great car with a great price.
