Update:
I'm about 50 miles away from turning 36,000 in my 2007 M3.
Goodbye warranty. *sniff, sniff* but it was just in time when last week it ended up back at the dealership for a new a/c system (which I had, had it in for twice and was told it was just fine), a new alternator and a new belt and tensioner.
Other than that, $12k worth of body work and glass repairs due to a tree falling on it (insurance covered), regular oil changes, a transmission fluid flush, a replacement wiper blade arm that started rusting this summer (covered by warranty) and a new set of tires it's been great.
Oh, and I hit a raccoon the other day and dented the front bumper cover ... another trip to the body shop is in my future.
