These guys were a dream. I've taken my 2002 M3 to them for an oil change and a burned out convertible motor - and both times, they went out of their way to give me a great price. I was expecting more than a grand for the convertible top - without labor even - but walked away for way less than that. These guys are nice guys, nothing shady about their business, and I've verified all their work myself. Good stuff. Way cheaper than the dealer.
