Edmunds' Expert Review

vehicle overview

Ford should worry about the Grand Prix. Loaded with standard safety features, and available in a potent supercharged, 240-horsepower edition, Pontiac's Grand Prix successfully blends form, function and performance into one very appealing and affordable package. The Taurus, by contrast, is little more than overpriced modern art.

Buyers can select from one of three available Grand Prix models: SE sedan, GT coupe or GT sedan. The SE sedan is powered by a 3.1-liter V6 engine good for 160 horsepower. Optional on SE sedan and standard on GT coupe and sedan is GM's 3800 Series II 3.8-liter V6, which kicks out 195 horsepower while delivering 19 mpg in the city and 30 mpg on the highway, figures that nearly match the base powerplant. GT models can be equipped with the GTP package, which includes a supercharged 3800 V6 that makes 240 horsepower. Last year, the GTP was not equipped with traction control, a feature that it really could have used to keep all those ponies in line. For 1998, Pontiac rectifies the problem, and traction control is now standard on all supercharged Grand Prixs.

Included with the GTP package is a transmission that allows the driver to select Normal or Performance shift modes. The antilock brake system includes thick rotors and state-of-the-art calipers for better stopping ability. Steering wheel vibration is reduced thanks to a cross-beam steering column support structure. All Grand Prix models benefit from long-life fluids and parts, such as coolant designed to last five years or 50,000 miles, and platinum-tipped spark plugs that last 100,000 miles under optimal conditions.

Interiors feature analog instrumentation and large, easy-to-use controls. The dashboard is busy looking in the Pontiac tradition, and is lit by a soothing red glow at night. An integrated child seat with a removable wash-out pad is optional on all models. Also optional is the Eyecue head-up display, which projects data for speed, fuel, radio and turn signals onto the windshield for easy viewing. The standard driver information center includes a tire-pressure monitoring system. Standard on GT Sedan and optional on GT Coupe is MagnaSteer variable effort steering, which uses magnetism to vary steering effort.

Dual airbags, antilock brakes and traction control are standard on every Grand Prix. All 1998 Grand Prix models meet federal standards for side-impact protection, and bumpers front and rear are designed to withstand a five-mph impact with no structural or lamp damage. Sedans feature child-safe rear door locks, and an integrated child safety seat is optional for all models.

Yes, Ford should be worried. Interest in the Taurus has waned in recent years because buyers have been drawn to more attractive and often more affordable alternatives. With last year's redesign of the Pontiac Grand Prix, we predict that the Ford battleship will take one more serious hit from the competition.

1998 Highlights

Supercharged GTP models get traction control, and new colors are available inside and out. Second-generation airbags debut as standard equipment.

Great Car
I am the original owner of this car and over the years it has been a very reliable vehicle. Currently, it has 160,000 miles and only minor issues. The HUD display used to dim out, but I fixed that by resoldering the connectors. Also the supercharger coupler required a change ( approx $50 DIY ). Minor leak around the oil pan and A/C needs service. But for a car that is 10yrs old with mileage, not bad and never left me stranded. BTW, for those knocking this car, I have seen new BMW or two stranded along Route 80 at times.
This car is definitely a good car 2 pull out on any day of the week, would not say it is commuter friendly its a gas guzzler. All and all it is a great car would give a strong recommendation for anyone considering this car
An Excellent Choice
S Martin,12/12/2006
I've owned this car for nearly 9 years and I'm so happy with it that I'm buying another GP and giving this one to my new 16 year-old driver. After 124k miles, nearly all of the electronics are original and fully function. No problems with window motors, window switches, windshield wiper motors, nor are there any leaky window or sunroof seals. No odd noises and no problems with the power steering. Original transmission still shifts well and the leather interior has held up wonderfully (looks almost new). No fluid leaks either and the engine is nearly as strong as it was the day I bought it. I still average almost 25 mpg (though I'll admit this is partly due to my non-aggressive driving)
GTP Lover!
I have owned my GTP for a while now. It is bright red with every option except sunroof. I love it! I would definitaly recommend this car to anybody. I have never had ONE problem with it. The only thing I wanted to replace before it got worse was the tire rod which could happen on any car. The performance is outstanding! Passing power is effortless and cornering is amazing! This car could honestly beat anything out there except for an LT1 or LS1 Camaro or Trans AM. Watch out FORD MUSTANG GT! All in all, if you can find a grand prix gtp, you should HIGHLY CONSIDER buying one! A++++++ PONTIAC!

Should I lease or buy a 1998 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.
