Dan,
They also rate contours like $hit and some people on here have had very reilable ones.
Our 92 SHO (MTX) was a great car, doesn't handle on rails but showed up a lot of stuff in it's day. I was looking at 2nd gen SHO's when I got my 'tour but couldn't find a decent MTX one. The ATX ones pretty much do blow. My friend has a 94 and it's a mess.
I wouldn't hesitate to get a 2nd gen MTX, especially if you don't mind doing some of the work, any car that age needs, yourself.
HTH,
-Pete
