Only thing that has gone wrong was my battery went dead.
Excellent car. Beautiful on the outside... Better on the inside. it has plenty of leg room, and seats 5 passengers.
The 3.4L engine has plenty of power (210 HP) and is excellent on gas.
Only problem I have had (only had it for a little while) was the battery dying on me. But since it was only a week after I got it the dealer came and gave me a new one on the spot!
I fell in love with the car when I first set foot in it. This is my first car, and after about a month I am completely in love with it... Next car will definitely be another Pontiac!!
I also have a 93 STE and I love it!!
I have a '91 Grand Prix STE! Love this car! Have had no problems.
I have a 1992 GP STE and have found only a few minor problems..
The front rotors were replaced after 3000 miles.
The HUD comes on when it feels like it... - suspect wiring connections.
Idle speed is >3000 when cold, but OK when warm - think this is leaky vacuum hoses.
Minor electrical problems - bad connections mostly.
Not bad as it is kept in the UK where our weather is wet most of the year!
Apart from that, Great car, lousy MPG (at $6.50 per gallon) 20MPG hurts!!
I have a 90' grand prix and love it. But I needed another care with less miles and I got a 91'. It is so sporty. I love it with the sun roof. It makes an excellent car for me and my family.
I love my car. It has needed a new transmission, but other than that no problems. Good strong quick car.
I am thinking of buying a 91 STE, it is in fairly good shape. I just wish it was a 2 door so I could get the awesome head lights, but that is no big deal. The windshield is cracked badly so I am going to drive the price down with that, they have it starting at 4500 Canadian, I hope to get it for 4000 or less:-)
