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.

  GTP is the pure excitement!!!!!!! - 2005 Pontiac Grand Prix
  By Grandman - April 24 - 3:33 pm

  This is simply the best vehicle that I have owned hands down. I feel like I own the road when Im dring the GTP. I tried the Maxima and Accord, but they didnt have the excitement or looks of the GTP. The GTP is one brilliantly designed top quality car. I have over 12,000 trouble free enjoyable miles on the GTP.

  Great lines with quick response. I have taken down a few of the competitors...sorry Monet Carlo, Im glad I didnt buy one! Too bad it is front wheel drive w/ no manual...oh well the rest is good to go.

  Eye-Catcher - 2005 Pontiac Grand Prix
  By Thunder - March 21 - 2:23 pm

  Blue-Green Crystal gets lots of compliments in parking lots, gas stations, etc. Great performance, but if the idea for bigger tires in the front really was to reduece torque steer, I dont notice much improvement over my former 98 GTP. Still, be aware of it and its not a problem. Very solid ride with little or no body lean into corners. City mileage hasnt worked out as advertised yet, though I only have 600 miles on it, so far. Hopefully itll get better than the current 14 mpg after a couple of thousand miles. Highway miles are decent (26mpg) and should also improve, soon. HUD is much better and more informative than older models. Exhaust? Aaaah, sounds like my old Z- 28.

  This is the thrid Grand Prix I have owned and I love it as with the rest of them. They are very dependable, comfortable, and sporty. The handling is wonderful and it drives better than any other car in its class.

  My Pontiac - 2005 Pontiac Grand Prix
  By Kolt - March 3 - 7:40 am

  I love this car! I never would have bought a Pontiac 10 years ago. The car is designed very well and the seats are very supportive. The ride is soft yet somehow sporty too. I love the throaty sound of the exhaust. Ive had three people in the last year comment on how they like the sound of my car. I often journey on 500 mile road trips and arrive refreshed. Now the back seat does feel like you are looking out from a well, but I prefer the seat right behind the steering wheel. The 28mpg rating is accurate. No hybrids for me when I can have the power and convienence of this engine. Hats off to GM for the first car Ive enjoyed in a long while.

  05 Grand Prix - 2005 Pontiac Grand Prix
  By SDouglas - February 27 - 12:50 am

  I have been pleasantly surprised by the quality and comfort of my Grand Prix; havent had to take it back to the dealership for anything except routine maintenance which is pleasant surprise after dealing with numerous recalls & problems with my last 4 (new) vehicles. Also, I drive a lot of miles & still enjoy driving the Grand Prix after a year. LOVE the color - Fusion Orange Metallic, enough gray already!!

  The car is both sporty and practical. It has lots of pep. I drove it in a snow storm and felt very safe. Front seats are comfy. Rear seats not so comfy for adults.

  Pretty Nice Car - 2005 Pontiac Grand Prix
  By adamb - December 21 - 6:03 am

  This is overall a great car. I get tons of looks while driving this car up and down the streets of my city. I think that these seats are really comfortable, almost on the level of my mas lexus. This car corners like a dream. Taking 25mph corners at 60 is fun and a breeze. (yeah im only 20 so this is something i do on occasion:)) The engine is great. Beat a newer mustang off the line last week, im sure he was happy about that. I think that the build quality could be better. lots of rattles. Also, have had it in the shop all last week for a problem with it not running right sometimes in the morning. Im not sure what this is, but they said the computer was out of date in it.

  Pontiac Grand Prix GT: Take another look - 2005 Pontiac Grand Prix
  By DMV - November 2 - 3:16 pm

  Looking forward to the release of Buicks replacement for the Regal, I kept looking at the Grand Prix. After driving both the LaCrosse CXL and the Grand Prix GT, the choice was easy. The GP-GT is more to my personal liking due to its crisp handling (for a midsize vehicle, it is great), and the responsiveness in acceleration, even though the LaCrosse & GP are built on the same platform and use the same powertrain. The GP is simply more sporty than its cousin from Buick. On a rercent trip, I experienced 31 MPG at highway speeds. The comfortable leather interior that kept away fatigue on a 5- hour drive: very nice! The Monsoon system would be worth the extra money

  Great Car - competitive - 2005 Pontiac Grand Prix
  By Greg - October 29 - 10:00 pm

  Originally looked at the LaCrosse but found the interior a bit boring and the responsiveness not as good as the GrandPrix... My wife said the LaCrosse was an "old ladys car" and saw the GrandPrix as sportier. She is right.
