I have been a customer of California Autohaus since 2008. Bob and Lavon diligently kept my wife's and my son's Range Rovers (2004 and 2000 respectively) running... and on any given day this was no easy task! They were always proactive and always looked-out for my best interests. Their timely and professional service enabled me to sell both vehicles four years later. I replaced one of the RR's with a Cayenne and took in for its scheduled maintenance and their new, very experienced (yep, he started on 356s and worked his way to current models) Porsche mechanic, Tom Muehl, stepped-up and diagnosed some issues and then executed the requisite repairs. Meanwhile, Lavon negotiated the path through the warranty company successfully and now, the Cayenne is in perfect running order. I will continue doing business with California Autohaus!
