I have had this car for over a year. I bought the car with only 41K on the odometer! Fortunately the car has some nice options: Hard top (no Vinyl)Trans cooler,dealer sunroof (still works) and G80 postraction. Interms of performance: The LT1 and postraction combo make for some accelation. Climate control is great-much better than the chill or roast options you find on standard caprice heater controls. power steering and suspension have a lot of potential. (i'll discuss later) The power sets and rear seat are nicely designed and give a comfort and space reminiscent of the old late '60s rivera's or le sabres. I even like the otherwise tacky LIMITED sidelights. They look distinct now. Here are some flaws: the stock suspension seems designed for elderly fragile drivers- as well the disc drum brake combo is effective but forces one to drive with restraint. As well, I had the touring suspension which seems utterly worthless except on flat highway driving in straight lines.
The quick fix- disconnect the air compressor, replace with cargo coil springs and gas charged heavy duty shocks up front and 9C1 coils up front with same shocks. in other words spend a few hundred bucks and the buick drives like a stock impala SS! By the way keep the 15 inch wheels and buy some 235 70 15's with T or V rating and you are golden! You will have all the handling you will need plus some durability for potholes etc.This simple combo helps at high speed.
