When Select opened their service center, I took my 911 there on a referral from an independent mechanic who had closed his business. Mark, the Porsche Whisperer, went through a detailed explanation with demo of the mechanism that was failing on my convertible top and, as a first option, suggested an inexpensive work-around that had the potential for extending immediate use, thus, postponing an expensive repair. He refilled the hydraulic reservoir with the caveat that it could last a month or maybe the life of the car-- no promises. So far, so good! I was impressed with Mark's knowledge; my wallet was pleased with his provisional solution. As others have noted here, the knowledgable mechanics, state of the art equipment, and pristine shop inspire confidence that this is a place that knows and respects luxury cars.
Today I took my MB S500 in for a regular service. Michael Kramen, the service manager, was his usual self-- that is, pleasant, upfront about expectations/predicted expense, knowledgeable, and efficient. Upon arrival, he greeted me with a cheery hello and the paperwork in-hand before I could even coast to a stop in the parking lot. He predicted approximately 90 minutes but it actually took a little less while I waited comfortably in the lobby with my laptop tuned into their wifi so that I could keep right on working. The price of the service was reasonable and without surprises. After the service was complete, Michael provided me with a printed list of the mechanic's notes on impending "normal wear-n-tear" items with prices-- things that do require immediate attention and do not pose a safety threat to the car or me, but are signaling potential problems that I should be mindful will require service in the near future. My budget appreciates the "heads up" to prepare for these normative age-n-stage repairs; I appreciate not being "up-sold" with scare tactics.
