I have owned a Porsche 911SC for 38 years and was looking for a new mechanic in Walnut Creek. I saw Prestige Autohaus, not far from where I live and stopped in and talked to Torsten. I liked that he seemed interested in my car and seemed experienced from our discussion. The next day, I stopped by with the car and talked to him again and made an appointment for oil service and another small item that has been on my list for a while. I had my appointment today and was very pleased with the work performed. I think I've found a really good and convenient place to take my car for service.
