Being new to the Tucson area, I researched german auto mechanic shops and selected Motorwerks based on their excellent customer reviews. My BMW E39 had headlight issues, needed brake service and had persistent undercarrige noises that could not be identified previously. The process from appt set up thru car repair was efficient. I was particularly pleased with the ongoing communication and diagnostic discussion with no up sell pressure. Costs were brought up early in the process so no surprises. The mysterious undercarriage noise was thought to be strut mounts that may or may not have been replaced at an earlier time so Mark recommended that I confirm this in my out of state records before pursuing this noise repair. Thanks Polly and Mark for the pleasant experience and the courtesy loaner!
