CSmotorwerks is by far the best independent BMW shop. I've been Christian's client ever since he opened the shop in Westlake Village. Maintenance work or repairs are performed better then at the dealership, faster and at very fair prices. As other reviewers stated, it is worth the extra few miles drive to get your BMW serviced by a highly trained specialist. Many issues with my 740i were addressed here: power steering, steering components (arms, bushings, etc), cooling system (radiator, expansion, water pump, hoses, etc), air intake (gaskets, MAF, sensors, etc),belts, brakes, oil changes, light housings, exterior trim installation, windshield gasket, etc. Everything done right the first time. Very highly recommended.
