2005 Pontiac Grand Prix GXP 4dr Sedan (5.3L 8cyl 4A)


Dreamed about this car a year before it was available. Great looking machine w/ the performance (HP, torque, braking, suspension) to support it. Surprisely controlled torque-steer (traction control) and instantaneous response from the beefed- up 4T65E tranny. The LS4's torque band is huge and pulls from one end of the tach to the other. The StabiliTrak Sport is simply amazing in the snow/ice allowing you to drive safely while having some fun to boot. The PBR brakes (huge drilled & vented rotors w/ dual pistons calipers up front) are gorgeous, responsive, and fade-free. After 6600 mi. we're averaging 20.2 mpg (trip computer) w/ mostly highway (using cruise control) driving @ 74mph.

Best Features

LS4 V8 HP & torque, StabiliTrak Sport, 18" Alcoa polished & forged aluminum wheels, PBR brakes w/ red calipers, respectable fuel econ (DOD), very supportive suede-insert leather seats, quad-tip exhaust outlets (w/ musclecar rumble), HUD, Monsoon stereo w/ XM, dual zone HVAC, spoiler, remote start...

Worst Features

RWD or AWD drive platform, 6-speed auto & manual trans availability, "true" dual exhaust, power w/ lumbar in front passenger seat, HID headlights.
