Just to let you know that my 1994 Buick limited 3.8 Liter has always got around 30-34 MPG since I owed her. She has over 190,000 miles on her now and going strong. Somebody is blowing smoke telling you that you only get 20 MPG.
I bought this car for one thousand dollars I've had it of nine months no problem at all I gotta say one of the best cars I've ever driven I wish I would of knew how good this car was before I bought my Ford in 2005 I never would of bought it. Driving my Buick is like driving on clouds.
I bought this car recently with only 78000 miles expecting a reliable car. It could just be a lemon, but there have been a ton of electrical issues. Performance-wise, the car is very disappointing. Many people would find the ride comfortable over bumps, but in reality, it has very poorly tuned suspension. There is hardly any damping so the car bounces far too much after hitting a bump. This coupled with very soft springs is a bad combination. When turning quickly, the body roll is very substantial. So much so that it could be a safety concern. In a situation where you had to swerve, the body develops so much inertia that loosing control could easily happen. Acceleration is surprising
Re-tune suspension by stiffening anti- roll bars, springs, and increase damping in shocks. Loose some weight. Increase steering feel (very numb as it is).
