My 3 liter Aerostar had almost 200,000 miles on it when I had to replace the clutch. My 94 Ranger had 180,000 on it when I bought it with a bad trans. The guy who sold it to me told me that it had 33 inch tires on it when he bought it and that he got it with less than 100,000 on it. The clutch wasn't shot but I replaced it anyway just because everything was apart.
