Thanks for the reply. 200k is a stretch I know. I didn't expect that to be a number people were seeing often, but it is the first number for a long shot clutch life that came to mind. My dad's old subaru GL ran 210k on the origional clutch, and my 91 subaru legacy turbo ran close to 200k before I replaced the clutch.
Anyways, the 4runner I'm looking at has 116k miles, so I'll definitely be asking about the clutch. Thanks.
