Thank you Mr Arnold for scheduling me on such short notice!! You did a great job diagnosing my engine light and solving the problem! So glad I found my new “go-to bmw mechanic” in Marin. What a relief. Best, 2006 325i.

Simply the best e39 bmw service in the Bay Area. Hill has more knowledge in his pinkie finger than most other shops have across their entire staff. Priced right for the quality of work he does.

Honest, reasonable mechanic. Those words are seldom used together in a sentence. Perfectly describes Bill though. 🙂

New to the area, took a chance based on favorable reviews. Found my local BMW repair shop for life. Bill answers the phone and personally diagnoses issues. His team including Patrick are highly knowledgeable, caring, and honest. Dont go here to cut corners. Go here to get the job done, done right, and peace of mind. Far cry from inflated dealer rates, but be aware of the sign posted, $145/hr labor cost. Huge fan of Bill Arnold BMW and trust my 535i with them any day.

Bill is a wizard under the hood. I bought a 1972 2002 tii from Colorado that was running rough so figured it was a fuel mixture / altitude adjustment issue. I did see from previous owner complaints of surging and stuttering on some previous repair bills. Bill identified it had the wrong spark plugs, the wrong distributor cap and then he dialed in the fuel injection. It runs like a top now. He really really know his stuff and he is super friendly and approachable too.

Not only did Bill diagnose the problem with my X3 immediately, he told me what needed repair immediately and what could be addressed soon. On a particularly rained out day after picking the kiddos up from school, he replaced the part I needed and sent us safely on our way in a matter of minutes. He and his staff love BMWs, you can tell, and they made us customers for life. Thank you Mr. Arnold

No frills, excellent service.

The owner of this shop (Bill) deals with you directly. He tells you what parts must be replaced today and which parts can wait. He seems very honest to me. He explains the need for the repair and gives you options on how to proceed. He delivers on time and on schedule! I have used him twice and I recommend him highly.Scott

Bill and his staff are the best. I am a self proclaimed picky car enthusiast and was nothing short of impressed. Honest, great pricing, efficient and most of all extremely competent.

Bill has been very helpful and candid with our cars needs. My wife even took it in at one point almost insisting that the oil be changed and he patiently explained the oil change interval on the latest model 3 series. Well go back for any further maintenance.

Friendly and knowledgeable, was very fair and didnt do unnecessary work to charge extra. Will definitely be coming back!

Great service. Expensive, but not out of line. They know more about BMWs than any mechanic I have tried. Replaced water pump, seals, back window regulator.

This guy knows his craft!!! And he can do it three times as fast as we can!!!

Responsible and caring, with the car and with your money too.

Great place even better staff

Honest and helpful.

My favorite mechanic of all time, when I get another e28, well...
