After 9 months and 5k miles I thought I would share my costs so far:
Current Miliage 28.9k

Preemptive Transmission / Filter change $350
Replaced Front control arms/joints to eliminate rattle - Improved feel of car also - $2k
Brake Light Switch - $50
2 oil changes
- First was just a drain and fill as it only had a 3k on filter $30
- Second (last week) - Why in hell don't they put the filter on top of engine like BMW?
Still 25k miles away from second timing belt service. Lots of good miles ahead.

Car runs and drives great - Really one of my favorite cars in the last 10 years - Worlds more rewarding that the 2012 BMW 535 M Sport Xdrive I had. Right up with the E39 M5.
