The 93 GS that I owned was as reliable as the sun rising every morning - hardly a problem in 80000 miles of ownership. I ran the miles up to just over 160,000. The engine used no oil between 3000 mile oil changes and was always willing to run. The body was as tight as any car I've ever ridden in, with minimal noise from wind.
My favorite thing about owning/driving this car was the 'habit' of it all. It was like moving your arm - it just did just what you thought it should. Reliability was outstanding.
I suppose you could improve on the GS by moving up to the LS, but the most glaring thing missing was cup holders. Also the road noise was a little louder than I thought it should be. The trunk also leaked after about 110,000 miles and just before I traded it the right rear door seals were leaking.
