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.

  GRAND PRIX GIVES YOU EXCITEMENT! - 2005 Pontiac Grand Prix
  By KEVIN PARKER - April 8 - 3:40 pm

  The 3.8L V-6s 205 Horsepower gives true excitement to this sporty mid-size sedan. The low end torque moves the Grand Prix across intersections with tremendous authority, leaving most cars behind! Most passengers ask if I have the supercharged V-6 that comes in the pricier GTP. Fuel economy averages 28 miles per gallon with highway trips averaging well over 30 miles per gallon! The front bucket seats are very supportive and hold your body in place when taking avantage of the twisty road ahead of you. The back seat offers above average passenger comfort and handles the child safety seat just fine. Pontiac has lived up to its reputation of excitement with this new Grand Prix as well as value!

  Time for a change... - 2005 Pontiac Grand Prix
  By SFeldman Nutley NJ - January 6 - 6:16 am

  My 99 Buick Regal LSE was getting up in mileage and I was attracted by the GM rebate offers. 04 was the last year for the Regal, so I checked out the LaCrosse. I was not thrilled by the syling and looked at the Pontiac G6. While looking at the G6 is saw the Grand Prix. I loved the exterior styling and noticed that many options on the LaCrosse were standard on the Grand Prix.

  Great car - 2005 Pontiac Grand Prix
  By Danfm1 - October 15 - 12:50 am

  The car is amazing - Pontiac has really improved their products and it can easily challenge foreign cars. The turning is tight, the engine provides plenty of power while sipping gas, there are no rattles and the interior quality is great. Its safe, good looking, and a great ride.

  A good ride - 2005 Pontiac Grand Prix
  By B at 45 - September 21 - 5:06 am

  My GT has been trouble free. Original tires wore quicker than I thought they should, but Goodyears I bought holding up good. Ive been very pleased with the gas mileage for this size of car. 17-31 MPG. Alot of remote start in Chicago winter or Phoenix summer and mileage obviously drops. 65 MPH on interstate and 30 MPG. 85-90 MPH on interstate and 25-26 MPG. Over 68500 miles and still on original brakes. Ill need them soon, can feel rotors have a shimmy during hard braking. Like the oil management system, saves oil, have gone 9000 miles on a couple of changes. This is a great highway vehicle. Quiet and quick when its needed. Good in snow when lived in Chicago. Great AC now in Phoenix.

  2nd Grand Prix First GTP - 2005 Pontiac Grand Prix
  By Phil - August 21 - 10:16 am

  This vehicle has all the power and sporty style a driver requires. The front seats are very comfortable. The controls are very easy to use but plain. The rear seat certainly could have more leg room considering how deep the trunk is in this vehicle. The truck is almost too large. The superchager certainly moves this vehicle and without premium gas. I have owned a 2002 Grand Prix GT and have NO repairs or warranty work. The sporty style is what I wanted and still remains true in the 2005. The interior is plain and cheatly made, the overhead garage door compartment has been broken and is currently held together with tape. I do not plan on paying $50+ to replace it. Inc. Interior Qual

  Get Back into NASCAR - 2005 Pontiac Grand Prix
  By Blacksheep - August 9 - 12:53 am

  This is my second GTP Supercharged. I had a 97. Reliability on both cars (97 & 05) is terrific. Having a fold down front seat has come in handy more then once. I replaced the mufflers with Flow Masters and new exhaust tips. $400 and the car sounds like it wants to go and looks better from the back. My son-in- law replaced the air filter with a K&N filter. My only regret is that I did not know a V-8 was on the way. Pontiac needs to get back into NASCAR. I plan to stay with Pontiac and if it goes the way of Olds I will leave GM. No matter what you do to a Buick it is still the car my 89 yr old father drives and many more like him. No thanks!

  Wow, what kind of car is this? - 2005 Pontiac Grand Prix
  By Russ - May 16 - 3:33 pm

  I get that question asked all the time. I dont know how to answer because its so different from the base Grand Prix that I often just say "GXP" and then the person who asked shuts up and you can tell they have no clue what a GXP is.

  A Great Steal - 2005 Pontiac Grand Prix
  By clarkb2999 - May 3 - 7:03 am

  After rebates, paid just under $14K. For that amount, it is a great car. It is responsive and engergetic in everyday driving, quick when pushed. Individual Map lights are absent on the Base model, which most base Korean cars have. Base stereo is weak. Still a bit too much hard plastic on the dashboard, though the layout/ergonomics are FAR improved from the previous generation. A generally great car, and even without the insane deal, I would happily drive it over the boring 4 cylinder versions of the Camry, Accord, Altima, or Mazda 6.
