I know there is a guy in SoCal Boards that has surpassed 250K already. I think you can find his personal thread on the Photos section of S2KI. Gavin as wall is well over 150k I believe.

As for my S, it is just a little over 100K. I think I stopped driving it as a daily when I got married back in 09. that is when I got my 90k service done.

 

A buddy of mine has over 315k miles. But I know there's one more with over 350k. Heard of the guy but don't know him. Stock motor and everything.

 

S2k is the perfect car for San Diego! Your car sounds like a great find.

I'm just a quarter inch under 6' 4" (and 185 lbs) and have been fine with the stock seat. Originally I spent a few hours looking into seat lowering options, but I didn't want to spend the money. I took my similarly tall friend's advice and just stayed with the stock seat and I've been perfectly happy. I can heel and toe fine. Street, auto-x and track driving have been fine. My helmet just clears the convertible top with a finger width to spare.

I did remove the sun visors. They're pretty thick, removing them gives you a little more upward visibility.

My feet are size 11 or 12, nothing too large. I drive 99% of the time with no shoes, as any shoe is a tight fit under there. I don't think seat lowering would help this much, though. For auto-x and track I wear some tight fitting shoes (rock climbing shoes, actually).

I'd really like to sit in a car with lowering rails to see what it's like. I live nearby, in Carmel Valley. If you find a way to lower the seat let me know so I can sit in it!

Good luck.
