I just bought a 300SEL 6.3 which is located in Lakewood, WA. The car needs work in its injection system. So far I've spoken to Daimler Automobiles in Seattle, Phil Smart Mercedes in Seattle, and Performance Automotive in Tacoma. I really want to be sure I find a shop that can fix the problem rather than just throw parts at it.

Since I live in Long Beach, CA, I have to do all of this via the phone.

Thanks,
Bill Berks
