Edmunds' Expert Review

With the elimination of the GT trim level, we would avoid the 2008 Pontiac Grand Prix. The competition and Pontiac's own new G8 are more refined and better all-around performers.

vehicle overview

A lame duck is an aging or otherwise impaired water fowl that has trouble keeping up with the flock and is an easy target for predators. It's also a politician who's biding his time in office until his elected successor takes over. As far as metaphors go, the 2008 Pontiac Grand Prix nails both lame duck criteria, as an aging midsize sedan out of step with its formidable competition that's about to be replaced by an all-new model. While the two vehicles will overlap for at least one year, the new Australian-made Pontiac G8 is for all intents and purposes the Grand Prix's eventual replacement. For now though, the Grand Prix limps on with even less feathers on its wings for 2008.

The supercharged 260-horsepower V6 that used to reside in the Grand Prix GT is no longer available, leaving the underpowered 200-hp V6 and torque-steer-happy 303-hp V8 as the only choices. It's like Goldilocks discovering that Baby Bear's "just right" chair is out for refinishing. Against midsize family sedans like the Toyota Camry and Honda Accord, the base model falls short in refinement, build quality and interior space. Against V8-powered sedans like the rear-drive Dodge Charger and Pontiac's own G8, the Grand Prix GXP also fails to keep up with the flock.

We suspect that Pontiac dealers will be keen to deal on the Grand Prix. As such, it might make for a decent choice for someone just wanting an inexpensive daily commuter with enough sportiness to entertain on weekends. But given its many shortcomings, however, it's probably evident that the Grand Prix isn't at the top of our "must buy" list. We suggest checking out its many competitors or its spiritual replacement, the G8.

Trim levels & features

The 2008 Pontiac Grand Prix is a four-door sedan available in two trim levels: base and GXP. The base model comes with 16-inch alloy wheels, full power accessories, keyless entry, cruise control, OnStar and a CD player. The GXP features a sport-tuned suspension, 18-inch alloy wheels with performance tires, an upgraded stereo system, heated front seats, leather upholstery, dual-zone automatic climate control and a head-up display. Most of these features are options on the base model, while both trim levels are available with a Sun and Sound package that adds a sunroof and a nine-speaker Monsoon stereo with in-dash six-disc CD player. Other individual options include a navigation system and satellite radio.

2008 Highlights

The GT model and its supercharged V6 are no longer available. There are no other significant changes to the Grand Prix for 2008.

Performance & mpg

There are now only two engines available on the Grand Prix. The base model features a 3.8-liter V6 that produces 200 horsepower and 230 pound-feet of torque. Revised EPA ratings for 2008 indicate it gets 18 mpg city and 28 highway. The Grand Prix GXP represents a huge upgrade, with a 5.3-liter V8 that pumps out 303 hp and 323 lb-ft of torque. Both models are front-drive and come with a four-speed automatic, with the GXP featuring a manual-shift mode. Pontiac claims the GXP will run from zero to 60 mph in 5.9 seconds, but in our testing we measured 6.7 seconds.

Safety

Antilock brakes and traction control are optional on the base model and come standard on the GXP. A tire-pressure monitor is standard on both trims. The GXP also has a stability control system. Full-length side curtain airbags are optional on both models. In NHTSA crash testing, the 2008 Pontiac Grand Prix earned five stars (out of five) for its protection of the driver in head-on collisions. The front passenger position earned a four-star rating. In NHTSA's side-impact tests, the Grand Prix scored three out of five stars (for front and rear occupants), but the car tested did not have the side curtain airbags. In IIHS frontal offset testing, the Grand Prix earned a "Good" rating, the highest out of four, while that agency's side-impact testing (with side curtain airbags) resulted in a "Marginal" rating, the second lowest.

Driving

On twistier thoroughfares, the 2008 Pontiac Grand Prix feels larger than most of its competitors, which is perhaps not much of a surprise when you consider that it's almost 10 inches longer than the Toyota Camry. In its favor, though, the Grand Prix is still fairly tight and tossable for a front-wheel-drive car. The base V6 is noisier than those in more refined competitors and fuel economy is less than average. The GXP is also not very composed, as the heavy V8 in its nose blunts the ability of the car to turn in crisply and make quick transitions. It's also rather thirsty and is prone to torque steer (the tendency of a powerful front-driver to pull to one side under hard acceleration). We used to recommend the supercharged V6 model, but alas, it is no longer available.

Interior

The Grand Prix features the last generation of GM build quality and materials, which not only puts it a few steps behind the competition, but behind GM's newer vehicles as well. The stereo panel is particularly out of date, while the surrounding pebbled plastics look and feel cheap.

A quick inspection of interior dimensions may seemingly reveal that the Grand Prix has comparable accommodations to other midsize sedans, but as Stephen Colbert might say, "facts can be deceiving." The rear bench is hard and situated low on the floor, causing a splayed, knees-to-the-ears seating position. This design is to counteract the sloping roofline, which still manages to chew into headroom. At least the back doors open up to 90 degrees, making access to the backseat more pleasant than actually sitting in it. The trunk does have a respectable 16 cubic feet of luggage-swallowing space, plus the rear seat and front passenger seat fold flat to allow a 10-foot Persian rug to ride shotgun.

I am writing this review on a 2008 Pontiac Grand Am that I own. I have owned this car for about two years and have only one bad thing to say about the car but other than that the car has been a great fit for me. I have owned the car for about five years. It has great gas mileage, great horsepower, it has needed only minimal repairs, and the only thing bad thing about it has been an issue with the ignition but that has been fixed. This is my first Pontiac I have bought and I don’t regret the decision one bit. Every day I have to commute about 20 miles to work, so most of the miles I have put on my car are highway miles. My Pontiac gets around 30 miles per gallon on the highway.

My 08 grand prix is 2 yrs old w/ 60k miles. I've only had it 2 days but so far it seems like a good car. The interior could use some work, I'm 5'7 and I feel like i'm going to hit my head on the roof w/ the seat completely lowered. On the other hand my 2 children cann't see out the windows in the back because the seats are too low. My son is 4'3, 5 yrs old and in a booster, the window placement is way too high. Plus I'm use to driving SUV's and I don't like how low the car sits I feel like I have to pull myself up out of the car. Time will tell I love pontiac and this is my second one. My sunfire lasted 7 years w/ tons of driving and little maintence hope this one holds up as well.
Runs and Drives but not much more.
driverEd!,09/20/2010
Purchased this with 30K on it and was excited for the 100K warranty. Too bad it does not cover anything that went wrong with this car. Fun to drive, exterior looks somewhat dated, but cool, interior is junk. Shift linkage jammed up and could not put car in drive, had to be towed. Heater vent fell out and split in half. Window seals on driver door leaks water, drips on window switches. Glove box handle broke and fell off, $165 for that part. Trunk seal leaks water, trunk gets moldy smell. Once and a while the engine won't start without cranking for over 1 FULL minute. Just another Union made piece of junk. It's for sale as of today!
GM Cheated Us
GMMan,10/12/2010
WE bought a used pontiac grand prix se from Iron Trail Motors in Virginia Mn with 26,000 miles on it. The day after we got it the car started to have problems. The dealer fixed a few thing but not the major issues like the paint falling off. that's right the car now has 49,972 miles and the paint is falling off. i called GM and took it to get looked at, they told us it was in an accident and repainted and now delamination has began.GM said they cant help us but there is no proof of any accident on the title. They said there's nothing they can do. So in all don't go to a Gm dealer or you might get a car thats been smashed then GM says "sorry we cant help you"and so did the dealership that did it.

Should I lease or buy a 2008 Pontiac Grand Prix?

Is it better to lease or buy a car? Ask most people and they'll probably tell you that car buying is the way to go. And from a financial perspective, it's true, provided you're willing to make higher monthly payments, pay off the loan in full and keep the car for a few years. Leasing, on the other hand, can be a less expensive option on a month-to-month basis. It's also good if you're someone who likes to drive a new car every three years or so.
