  My first Pontiac - 1998 Pontiac Grand Prix
  By Dre - November 13 - 3:16 pm

  My first Pontiac and I love it. The power this thing has along with the ride comfort is just amazing. Me constantly driving to the coast, a good 300 miles, I get great gas mileage. The city on the other hand the mileage just drops to about half of what I get on the highway. All in all its a great ride.

  I am the orginal owner of this car. This is a great car to drive and it looks great. Unfortunately the build quatity is poor. This car has been in the shop over 50 times for warranty work. I am very luckly that I purchased an extended warranty on this vehicle.

Power window switch replaced;$80. Automatic dimming rearview mirror stopped working;havent replaced. Comfortable for 4 adults. Decent gas mileage if not driving too hard.

  Great fun car -little things at 6 years - 1998 Pontiac Grand Prix
  By Charles Low - February 15 - 1:46 am

  I have loved owning and driving this car. Little things at 6 years like transmission sometimes stuck in Park (requiring an easy maneuver with a screwdriver, but still..), radio LCDs malfunctioning. But generally a very good, reliable vehicle, incredible sound system, very tight, responsive handling, low driving position, extremely "sticky" on the road. Some gaskets have needed work. I think the major Asian producers are indeed better for reliability, so its time to switch, but I have really enjoyed this car. I know the GTP is noticeably peppier, but I have never felt short-changed for power in the GT.

  98GP Still Going Strong - 1998 Pontiac Grand Prix
  By stragger - January 10 - 10:00 am

  My Grand Prix came to me as a company car, but I feel in love with it and bought it when it reached 36,000 miles, the company limit. I have always felt like this car fit me like a glove, and its performance, while not a sports car, has always been more than adequate. Aside from some quirky electronic anomolies, it has been totally problem free. My best surprise is that I still get 28 mpg on a the highway at a steady 70 mph. I cant see buying a new car yet, since this baby still meets all my needs.

  My second GTP - 1998 Pontiac Grand Prix
  By Keith - May 5 - 8:26 pm

  This is my 2nd GTP. Both have been great cars with the second reaching over 110k miles before trading it in. Having owned both 2d and 4d I recommend the 4door. You have plenty of back seat space so it is just easlier to access the back with doors. Nice power when needed from the supercharger, climbs hills with no problem, does well in rain and snow. The car is solid inside and out. No rattles!!! The radio display in both cars do some weird things!!! The HUD(heads up display) display is the best feature. This is a 98 and I yet to understand why this feature isnt in any other cars but the GP and Bonn. I would think this must have technology would be in most cars by now. So why not????

  Best car I have owned - 1998 Pontiac Grand Prix
  By McLaren - December 19 - 11:53 pm

  My Pontiac Grand Prix was six years old when I bought it in 2004. It had been bought new by an elderly woman who only drove it to church on Sundays, and always kept it garaged. It had 17,000 miles on it. This car has been phenomenal. In the 4.5 years since I bought it, it has had no major repairs. Very reliable. Aside from reliability, the car is Very comfortable. It has all the options, leather, power, heated seats, excellent sound system. I have taken this car on several cross country trips, and the ride was considerably more comfortable than in my old Ford. Overall this car was an excellent buy. Comfy, reliable, fun to drive. I recommend.

  OK, so it was a former Mary Kay car... - 1998 Pontiac Grand Prix
  By smoo4asw - November 14 - 3:46 am

  ...and it was pink and had the bare minimum feature set. It did safely deliver to me the 128k I love so much from Cleveland (where wed go to buy its replacement when it crapped out on us) and it didnt have the :-(analog) cellular network driven OnStar crap that Verizon Wireless can bollox up at will. What it didnt have was durability. It was reliable until it broke, but when it broke, it was shot and that was all there was to it. Needless to say we werent going to be burned by Pontiac a third time (my Grandmother had a Phoenix and it wasnt even reliable!) It did its bit, but Im glad its gone for scrap.

  98 GP GT Coupe - 1998 Pontiac Grand Prix
  By john344 - October 21 - 2:00 am

  This is my 3rd GP. I love this car, if only GM would use better quality interior parts. My door panel on the drivers side is loose, cheap plastic on dash. Engine gaskets are poor quality and Ive just had $1500.00 worth of work done on the engine due to leaky gaskets all over the place. Other than that, its a great car, fun to drive, looks hot with the dual exhaust...standard 17 inch rims would be great. Whats up the headlight assembly on these cars?? Mine is loose & wiggles around, was filling up with water every time it rained until I took to a repair shop the they silconed the edges to stop the leaks (the dealer would not fix this under warrently).

  Fun to drive! - 1998 Pontiac Grand Prix
  By GPFan - May 21 - 10:00 am

  My car has about 85,000 miles on it. The performance, comfort, and styling in general are great. However, even though Ive taken excellent care of my car, Ive had around 3,000 in general repairs over the past year. My headlight lenses went 1st - Apparently the glue used to hold them on the headlight assembly dry rots, and they can fall off. But, you cant buy just the lenses. The blower motor and resistor - for the interior vents needed replacement. Also, about a month ago, my brake calipers went bad in front. At present, its in the shop getting its transmission fixed, and the upgraded parts - which is by no means cheap. I dont want to scare anybody, the cars really been great.
