I recently bought an '87 944 and was shopping around for a good Porsche mechanic when my clutch master cylinder started leaking (as this is my daily driver, I needed my car fixed immediately). When I called the Porsche dealership in Livermore, while some folks had been kind, I was eventually put in contact with a rude receptionist who told me, flatly, that I couldn't be seen for a week. I then discovered Kahler's through Yelp, gave them a call explaining my situation and they were able to see me the very next day. Everyone I talked to was courteous, friendly, and, even now, remember me and my car. The workmanship for the repairs was top-notch and they used the best parts and fluids (ATE brake fluid in the case of my clutch). All-in-all I'm a very satisfied customer and will definitely return for any other necessary repairs.
