CS Motorwerks is a gift from above for those of us with BMWs that are out of the dealer service period - in my case an '04 M3. These cars can start getting expensive to maintain, especially the M3 with its periodic valve adjustments. CS Motorwerks isn't cheap, but they charge considerably less than a dealer, for much more diligent work. Christian and his team have all the BMW certifications and training, but are focused on delivering value to their customers, not to a large dealer. They will do what needs to be done, not what will make them money. They will do it very thoroughly and well, and they will do all this at a lower rate than a dealer would charge. Having found CS Motorwerks (conveniently only about a mile from my house), I feel like I'll be able to keep my car for a few more years, knowing that it'll be well taken care of.
