Excellent work, immediate appointment, fast turn around, courtesy and professionalism from start to finish from Greg and Brett. In her youth, my e34 535i was serviced at Dinan in the Bay Area, and now, after many years of faithful service and well over 300,000 miles, needed a bona fide expert to diagnose (a drivability issue) and get her back in tune. Not inexpensive, but a great value and worth every penny. Thanks for restoring her turbine-like smoothness and power. We will be back.
