After owning a number of cars and trucks, I purchased this Suburban for highway trips and light off-road duty. It has the dual A/C and leather, black exterior with gray interior. It has had all synthetics since new, and it was very well taken care of.
I love this truck! No other vehicle I have owned is as useful and comfortable as this one. The 350 is a slight gas hog when you put your foot into it, but it is a small trade off. I am 6'4", and have no problems on cross-country journeys. It's actually more comfortable than my office chair!
The recall on the wiper motor is actually for the motor's circuit board, which cost me $14 and about five minutes to replace.
This model, in my opinion, is the best year for Suburbans. The dashboard is the wide, clean style, and all of the controls are upfront and simple. The later (95+) years had strange dashboards, cheaper control panels, and interior panel squeaking (Canada parts) that I don't care for. Previous model years (1991 and back) are too dated, and drive like bricks. The 1994 feels almost nimble by comparison. Many drivetrain parts are easy to find and relatively cheap.
The 350 motor is the one to buy, because the 454 is a serious gasoline eater, and best suited for towing. I have the extended range gas tank, and have easily gotten 600+ miles per tank.
The key is good maintenance from day 1. Whoever has trouble with these trucks just didn't maintain them (oil change, filters, fluids, etc.).
If you find a 1994 SLE in good shape and need something that will be around for a long, long time... buy it.
