This is not really a reasonable response. 93 is the first year - just because 93-97 is the first series of the vehicle does not mean that all of them will have problems. The changes to the 2nd generation were signifigant enough that you could apply the same logic. Would that mean that a 2005 would be unreliable? ;) Furthermore, unless you want a Supra, you will not find that engine or the RWD layout in any Toyota car. I have a 94 with 135k on it and the only major probkems I have had are a broken window regulator and a stripped starter. And whats this about "buying a used car other than for looks is not a good idea"? That just plain does not make sense. I would buy mine based on a combination of condition, performance, value and, yes, looks.
You can't go worng with a 1st generation GS - just make sure that you wait for the right one and mare sure that maintainance was done throughout its life.
