Or, they get abused. I've had very old and beat-up Celicas from the early 70's that were STILL ultra-dependable. But all the used ones I had were severely abused -- the car seemed to built for messin' around with - great fun to work on. And whatever I fixed stayed fixed.

In a road test summary sometime in '94 or '95 the Supra beat a 911 in acceleration, braking, and cornering. Not bad. And they won't break the bank with maintenance.
