Review of the 2005 Pontiac Grand Prix

  • Fast and fun to drive, the Grand Prix is still too rough around the edges to steal the hearts of import buyers.

  • Safety
  • Pros

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

  • Cons

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

  • What's New for 2005

    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.

Lots of fun

Vehicle: 2005 Pontiac Grand Prix GTP 4dr Sedan (3.8L 6cyl S/C 4A)

I purchased my GTP this month from my company. It has been my company car for four years and I've now put 117,000 on the clock and still a sweet ride without any major issues.

This car is crap

by on
Vehicle: 2005 Pontiac Grand Prix GTP 4dr Sedan (3.8L 6cyl S/C 4A)

Gee. What DOESN'T work on this car. Paint was peeling off after 2 years and now it has leprosy. Water pump needed replacing after 2 years. It's burning oil like a drunk BP CEO. The cheap plastic on the inside is worn off everywhere you put your hands. The leather seats are fading and tearing. Oh. And the stupid key fob won't work. Avoid this car. Avoid Pontiacs. Avoid GM.




Compg package makes big difference

Vehicle: 2005 Pontiac Grand Prix GTP 4dr Sedan (3.8L 6cyl S/C 4A)

My GP is equipped with the CompG performance package which includes: Head Up Display, Tap Shift, higher gear ratios, stiffer rear sway bar, and red brake calipers, maybe a few other things. The gear ratios dramatically improve acceleration and the sway bar makes this thing handle like a dream. It still maintains a quiet comfortable ride on the highway but is rigid during spirited driving. My biggest complaint about the car is the shifting performance in standard automatic mode, it just doesn't downshift quickly enough and lets the RPM fall well below the power band before it switches to a lower gear. This is alleviated by the Tap Shift system which will let you shift manually.




More than meets the eye!

Vehicle: 2005 Pontiac Grand Prix GTP 4dr Sedan (3.8L 6cyl S/C 4A)

The biggest bang for your buck! A refined machine that is easily underestimated. The exterior is sweet and the interior great. The interior design is made for the driver (that is the purpose of driving, right). I hate how the imports overly centralize the dials and in some cases the gauges right in the middle of the car. The interior is simple and not over done like the imports. Their designs tend to be a lot busier. The power is just right, handling great.




Better than good, but not

Vehicle: 2005 Pontiac Grand Prix GTP 4dr Sedan (3.8L 6cyl S/C 4A)

JD Power rated this vehicle as a good buy for reliability and I have to agree. I've had only two minor issues that were quickly corrected under warranty. Very comfortable around town and on the highway. Acceleration with the supercharged engine is excellent, as is braking. This is a large vehicle, so handling is good but not great. Fuel economy is in the low 20s with mostly highway driving; nothing close to the 28 mpg listed on the window sticker. Interior materials are a mix of good to cheap, with some areas nicely padded and textured; others are cheap in feel and durability. Red illumination of instrumentation is very appealing. All controls are easy to operate and very intuitive.




Happy with my comp-g

Vehicle: 2005 Pontiac Grand Prix GTP 4dr Sedan (3.8L 6cyl S/C 4A)

I have now had my 05 Grand Prix GTP Comp G for 2 years and 32,000 miles. I can't complain. Build quality and reliability are excellent. The s/c 3800 is fantastic! Instant power when you need it, mash the gas and hold on. Average 24 to 25 mpg overall on mid- grade fuel. This car handles the twisties with ease and glides over the highway. Handles the Vermont winters with no problem due to a set of Blizzacks and Stabilitrak. Huge trunk, excellent heated leather seats, and sound system. Lacks a bit on headroom though and rear legroom can be tight. Installed K&N filter. Overall, a good little daily driver and nice upgrade from my previous Grand Am's. Can't wait to trade up to a V8 GXP!
