[pothole]

Even if you're right about US owners barely breaching 2k rpm (and gotta be honest, don't really buy it!), here in the UK it's a dead cert most Boxsters will have spent tons of time passing through that rev range.

If you're right, there'd be an epidemic of IMS failures in the UK. But I've been using Boxanet forum in the UK for three years, loads of users, just a couple have had IMS failure in that time. Still can't see this is what causes the failures.
