Had to replace the rear struts after getting stuck in a snow drift.
Water pump had to be replaced.
Factory sound system was poor and I replaced it with a CD player.
Tear in the passenger side front seat.
Driver door power window motor is weak.
Rear window defogger doesn't always work well.
This is a great, reliable runner. It may be older, but it has power and good gas mileage.
I agree with your comments on the 1991 Buick Regal. I have one and it runs very well. I 've had it for 2 year now & other than the normal maintenance & replacement parts the only real problem that I've had with it was the ABS. Recently I've had a problem getting the doors open. They're either frozen or something else is wrong. On the passenger side, the key turns in the door knob, but the door doesn't open at all. The drivers side won't open either. I've tried WD40, hot water & deicer...I'm about to try to heat up the key to try to open it. But other than that,,,, I've enjoyed my Buick.
Can.
