Is it really mandatory that a BMW dealer do your service work to maintain the factory warranty? I have added a sidecar to my 04 Montauk and just had the first 6K service at a brand new dealer here in Miami, FL, and I just was not too impressed. I have a local mechanic who is excellent and would like to use him but do not want to invalidate warranty. Any help would be appreciated.
