I had a '92 SHO for two or three years. It had 170k or so on it when I bought it, and 186k or so when I sold it. I autocrossed it for a full season, took it to the drag strip, abused it on the street, and drove it on the daily commute/weekend roadtrips, etc. It only left me stranded once thanks to a dead fuel pump, and I was able to limp it home when the quill sleve around the TOB exploded during a 6700+ RPM hard shift into second.
The engine is a work of art. I still long for those noises to come out of the engine compartment of something- anything- that I own.
The rest of the car was very 'meh'. I had some issues broken engine mounts and front strut mounts, but these were the result of neglect by previous owners and high miles. All of the interior electronics seemed to take a sh!t at one point or another. Window switches, brake light switch, seats, etc... All junk. The leather was cheap and did not wear well, and I really wanted to installed some cloth seats from another Toreass, but never got around to it.
As a whole, I'd own another one, but I'd want one with lower miles and the first thing I'd do is replace the dampers and springs with something more aggressive. It was easy enough to work on, IMO, but I never had to do any internal engine work on mine. With enough extensions, you can do a tuneup without removing the intake, despite what people may tell you. Replacing the fuel pump was as simple as dropping the tank. All of the Ford parts will probably break, but you can get them from most any Sable or Taurus at the junkyard.... and we all know how plentiful those are.
