Currently 67000 miles on chassis, 9000 miles on engine.
Engine replaced by dealer at 58000 miles due to leak traced to an out-of-round intermediate shaft bore (by .07mm).
Factory bearing in both engines.

IMS seems fine
63,000 on 2003 C2 Cab. Runs great, but plan on doing IMS when clutch is replaced.

'99 C2 6-sp coupe, 94,500 miles and still ticking on factory original IMSB and RMS and clutch. No leaks. No issues. Have owned this one since 2004. I bought it when it was five years old and had only 6,000 miles at that time.
Plenty of city, highway, and track time (recent long trip, and track weekend in the last two weeks).
Three previous 996's (1999 bought new, 2001 bought new, 2003 bought new). No IMSB issues with any of them.
I only voted once.
