Overview & Reviews

The Grand Prix gets more muscle for '99 with low-restriction air-induction components giving the naturally aspirated 3.8-liter V6 five more horsepower, to 200. This engine is standard on the GT (sedan and coupe) and optional on the SE sedan. A traction control indicator and on/off button are now standard on GTP models. Minor revisions are in order inside, with front-door courtesy lamps and a six-speaker sound system now standard, and an eight-speaker Bose audio unit and OnStar mobile communications system optional. Outside, a rear deck spoiler is standard on the GT model, and two colors have been added to the 1999 exterior paint chart.

• Strong powertrains, sporty styling, fun to drive.

• Overstyled interior, cheap-looking dashboard plastic.

  A drivers car! - 1999 Pontiac Grand Prix
  By GRTFUN - October 23 - 12:43 am

  I really enjoy the great handling, heads up display, the way it hugs the curves, and the heated leather seats. My car was fully loaded and well taken care of. No complaints.

  Batmobile, Tank, Grand Prix Coupe - 1999 Pontiac Grand Prix
  By midwestboiler - September 17 - 4:49 pm

  This was my first car, and it was a great first car. Unfortuneatly, I was rear ended and ultimately had the car totaled. The time that I had it though, was very enjoyable. First, a V-6 engine allows for this car to be borderline over the top with power, but that didnt bother me. The problem with all of the power was that the car averaged about 18 mpg. The 12 gallon tank also forced me to have to fill up more often than I would have liked. I had leather seats and they were very comfortable. It was very easy to carry 4 passengers in the car. While the doors were huge, it allowed much easier access to the back seat.

I have enjoyed the car, but am getting tired of it. The car now has significant squeak and rattle and the exterior is showing signs of rust. I will drive the vehicle until the next transmission failure, which I anticipate at 200k.

  Slightly Disappointed - 1999 Pontiac Grand Prix
  By Sad about GP - February 2 - 10:00 am

  Overall, I have loved my GP GT. Style,fun,etc. However, after numerous trips to the shop (replaced rotors, tie rods ends,etc. more than once) am getting disappointed fast. Has numerous rattles on the inside and the door panels are not on tight. I hoped this would be a car that would last me 5 -6 years (150,000 - 180,000 miles) but we are getting ready to sell it just because of all of the little problems, rattles and fear of whats next. Wont wont buy another one. Have test driven the new model and it seems to have the same poor interior build problems.

  If It Wasnt For the Windows - 1999 Pontiac Grand Prix
  By lmojo - December 15 - 10:00 am

  This has been a great car EXCEPT for the 2 window and now 3 window mechanisms Ive had to replace. Without warning, my windows stopped going up they only went down and stayed there. Now, I trying to decide whether I want to replace another window mechanism or just bou another vehicle!

  Very Happy - 1999 Pontiac Grand Prix
  By Simon - December 7 - 2:00 am

  I wasnt hestitant at all when buying this car(GT 4dr sedan). I knew I was getting a car I could be comfortable in. Its big yet very quick, agile and comes with dual airbags for safety. So far I have been getting 24 to 25 miles per gallon, not sure if I am misreading other websites that claim 28 to 30. So far this car has given me exactly what I needed, comfort, acceleration, safety and did I say comfort.

  Nothing but trouble! - 1999 Pontiac Grand Prix
  By Irina - May 28 - 7:26 am

  Purchased it with 112K MI. Immediately had to fix the front axel, half a year later fuel pump went out, another half a year later torque converter had to be worked on (1500 price tag), breakes needed work too, then engine on the powerwindow broke. AC had to be fixed. Every time it rains water gets in the trunk and under the drivers sit. Windshield had to be replaced and since it has a display on it it was expensive! Now the torque converter broke again! And its only 143K now! I put in repairs more then I paid for the car! I never abused it, did all the maintenance and will never ever buy it again or recommend to anybody I know.

  My Blue Bird - 1999 Pontiac Grand Prix
  By jackrussel420 - May 20 - 10:58 pm

  I have a 1999 Pontiac Grand Prix SE with the 3.8 Liter motor and I have to say it is a fast car, for being just the SE anyways. Ive gotten up for 115mph in under 10 seconds! Engine has oil pressure problems anyone know why? other than that the only thing that has gone wrong is I had to replace a window regulator which is typical for any car these days. Oh and did i mention mine only has 47,000 miles and it is 13 years old!

  Go-fast - 1999 Pontiac Grand Prix
  By RH - March 15 - 10:00 am

  The only bad experience I have had so far with my Grand Prix is that it is put together so cheaply. The interior doors panels need to be beat back into place a couple times a week. The dash and over head console have so many squeaks and rattles, it is enough to drive you crazy. I get great gas mileage, 24 avg. overall and the car has plenty of power for the average driver.
