Bought in 2002 used with 49k miles, trading it in now 05/2005 with 109k miles. Very fast car, you'd never expect it and it always shocked everyone. I can be rolling 10mph, punch it and still smoke the tires. Sorry to see Buick stoped making the GS. Engine is great, no problems, oil still clear after 6,000 miles. Big drawback is fuel economy which totally stinks in city driving. But car has lots of gadgets, very comfortable, a hot rod and a luxury car combined. Monsoon stereo system is awesome.
Power - the fun of blowing people away with it who wouldn't look twice at the car as a performance vehicle. Monsoon stereo is fantastic. Lot's of gadgets and extra's.
The wiring is screwy for the power windows, Driver's side opens whenever you start the car.passenger side doesn't work anymore. Frequent trouble with getting key out of ignition. Fuel economy stinks.
