My car is a 2006 BMW Z4M. Usually I like to do my own maintenance, but when it came time for the valve adjustment and VANOS maintenance, I let the professionals take over. Derrick and the gang at CMW are awesome. The shop is clean, people are friendly, and service there doesn't come with the "just ripped off" feeling you get at the dealer. I've already refereed a few friends, and I'll continue to do so.
