About Us

Precision and Excellence

The experience, knowledge, and expertise to properly care for your BMW or Mini

We are a specialized shop that focuses on technical excellence and unparalleled customer service. Outfitted with the latest high-tech equipment and precision tools, we offer the best service for your BMW or Mini. Our technicians have been serving the North Valley for over 30 years. Rion left behind his 10 years as a BMW Dealer Master Technician in 1989, to start his independent BMW (only) service and repair business. Having more combined BMW experience and BMW-specific training than any other service facility in Northern California, we offer you service that stands out far above the rest. Please ask to see our credentials – they are based on fact – not “hearsay” or wishful thinking. Based on our reputation, even our name has been “imitated” locally, but of course, our level of service, knowledge and expertise has never been “duplicated”.
