I test drove a '92 with torsialastic suspension when my parents were shopping. They drive and ride extremely well. For the passengers, they tend to loose perspective that they are rolling down the road. Something else that is nice is when you look underneath, the whole bottom is enclosed as one piece. Also there is no frame, so your basement storage is unobstructed. Just a lot of wide open space underneath. Now if you have the option, you can also at least look for the '94 and newer with the 6 speed.
As far as long term cost, Brett Wolf owned a '94 (I think). He has stated that his biggest expense over time was tires. Other than normal maintenance, he really did do anything to it. He also installed air tabs and was getting a little over 11 mpg long term average.
