Overview & Reviews

Option packages have been shuffled a bit, as have the wheel choices. New radio units include a CD/MP3 player and a DVD-based navigation system with six-disc CD changer. Remote vehicle start is now available in all models. Late in the model year a 303-horsepower V8-powered GXP joins the lineup.

• Strong V8 and supercharged V6, nimble handling, attractive gauges, easy-to-use controls, big trunk, fold-flat front-passenger seat.

• Build and materials quality still needs some work, tight backseat, noisy engine, not enough storage or cupholders.

  I just purchased an 05 Grand Prix GT great car at a great price with the employee discount saved almost $7000.00.This is my second Grand Prix GT we also have an 02 which after 75000 miles has yet to give us any problems.I test drove many other cars but came back to Pontiac.For the money I couldn`t find a better equipped car.The Grand Prix GT for us is a nice combination of good looks power and reliability.

  V8 Bang for the Buck Winner - 2005 Pontiac Grand Prix
  By APR - December 16 - 8:30 pm

  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 LS4s 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. were averaging 20.2 mpg (trip computer) w/ mostly highway (using cruise control) driving @ 74mph.

  Solid - 2005 Pontiac Grand Prix
  By Kurls1800 - December 6 - 12:50 pm

  My GP has given me 5 years of great service . I did have a front rotor warpage issue early on and just decided to replace them. Otherwise, just change the oil and other common maintenance. Sad to see Pontiac end its production of Grad Prixs. Love the Pontiac red dash lights.

  Lots of Miles - 2005 Pontiac Grand Prix
  By Michelle - September 10 - 6:10 am

  I love this car. I love the way it handles, it feels like a luxurious smooth ride especially compared to my fiancees Grand Am. I love the way it looks, and the interior design. I have had a few problems though, the transmission needed a complete overhaul after 34K miles. Now I am having brake and traction system problems at 41K.

  Mid Life Dream Car - 2005 Pontiac Grand Prix
  By jammerman - July 28 - 5:03 am

  Saw the Grand Prix GT at Auto Show, loved the sportiness, but didnt buy - boy am I glad! When GM offered the employee pricing, discovered Pontiac had released a more sporty, upscale GXP - basically a GT with the V8 and all the sporty options (mags, chrome highlights, etc.) with the slightly lowered profile, this car screams speed! Everyone on my friends are green with envy. Nice throatty growl, instrument cluster well placed. TAP shifter makes it a fun cruiser.

  From 02 Envoy to 05 Grand Prix - 2005 Pontiac Grand Prix
  By clamp man - May 30 - 8:43 am

  Grand Prix GT, Great value, a lot of fun to drive, affordable, fast enough, great throaty exhausy sound from the dual tailpipes. Nice and tight bucket seats. A lot of utility included with the fold down rear and front seat.

  Huge Fun to Drive - 2005 Pontiac Grand Prix
  By Naples, FL - April 6 - 4:13 am

  0-60 in under 6 sec, pretty impressive for a 4 door grocery getter. The engine makes beautiful music, unmistakable V8 growl from the tailpipes. Very responsive handling while not completely sacrificing a comfortable ride-the engineers found a good balance. Pontiac is marketing more stuff to the enthusiast lately, they can be proud of this one.

  2005 Grand Prix GTP Comp G - 2005 Pontiac Grand Prix
  By B4crask - March 31 - 10:00 am

  This is an awesome car with excellent handling. It looks good both inside and out. The supercharged engine has the power to get you around anything on the road. Good old American Muscle! Glad I didnt get the Maxima...... I paid $1500 under MSRP and then got a $2000 rebate on top of that. Dont pay MSRP. You dont have to. Try getting Honda or Toyota to do that for you when buying one of thier boring little cars.
