I had owned a '90TT from 45k - 93k, only one problem ever - the rear main seal at 88k. My current '95TT k has 56k and i've had no problems other than ones created by me (electrical). My brother has a modded '94 SupraTT and is plagued with electrical problems. I also had a '94 RX7TT and surprisingly had zero problems - the car had 35k. In general, they're trouble free until you start messin' with sh*t.
