I bought this car because I needed a four door due to 3 kids. Now we drive it all the time. The gas mileage is great for an older car but it runs like a dream. I can't even tell the engine is running. And passing power is amazing. State troopers use it, but there is a reason they do. It's pure fun to drive and comfy as a warm blanket on a cold night.
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.
Although I bought this car as a stop gap measure (as my other car blew its trans). I have been ok with this one so far. I have a bad spine due to injury, and the ride of this car is very good for both short and long hauls. I am involved in my sons (youth) fraternal oganization and frequently my car serves a bus for teens and early twenties. Even on three hour rides to events, no complaints and everybody has room.
Interior lighting, Lumbar support (power), and trunk size.
Fuel mileage? whats that??? If this car has any cup holders, I still cant find them after 3 years! So cup holders would be nice.
