I live in the southern California, {Covina to be exact) and I need a good, honest, experienced mechanic.
I've chatted with the BENZDOC and he's the best mercedes mechanic I've ever talked to, but he's in N.Y. So if any of my fellow W140 owners in southern California, know a good mechanic that's not a cheat please let me know...
Bauer Imports in Glendora..I live in glendora and you in covina, practically neighbors. They are right off of grand and foothill. Anyway these guys do a real great job, and are extrememly professional. Ive seen them do everything from simple oil changes to replacing an entire head. The owner and cheif mechanic is a gentleman by the name of Andres. They have fairly reasonably pricing, you should check them out. tell them you were referred to by Chris Iglesias, we bring them lots of business!
best of luck to you
