I used to have a 99 Boxster, bought at 54k miles and sold at 80k, and missing it dearly. I've read and (hopefully) understand what I'm getting with a high mileage Boxster. I don't need a car, often, so this would be a weekend getaway vehicle.
Looking at a 2002 Boxster S with 119k miles.... oil changed every 14k (

), full leather, heated seats, xenon, etc.
Car needs:
New brakes (owner says rear, but I presume all)
Coolant reservoir
Blinker stalk replacement
Paint cracking on front bumper
Owner was quite tricky to speak with as he is sick, so I wasn't able to grill him completely. Chances are it's going to need tires and a once over, but one thing that stood out to me was that he said it's never had a clutch changed; my Boxster with 80k had never had a clutch change (none of my cars have), but 119k seems like a long time to go.
My questions are-
What''s the longest you have gone without replacing the clutch?
At $5,500-$6,000, please tell me this is a good idea.
