So I'm looking at a variety of cars, and one that keeps popping up to me is a 2002 BMW E46 2-dr M3, automatic/SMG transmission, with between 60,000 and 85,000 miles on it. I'm seeing a few in excellent condition for very good prices. I'm looking to use it basically as a daily driver, to work and back and what not.

Question - what do you guys usually pay for yearly as far as maintenance? I read the maintenance thread and it helped some, but I'm wondering if any major problems have jumped up with this model of M3 that I should consider when looking to buy.
