I highly recommend Ralph's for Porsche related service and repair. Ralph is a highly experienced Porsche Specialist and I knew this because I had called in with some OBD 2 codes - P0410 and P1411 that was showing up on my OBD 2 device. He instantly gave me the full description of the problem. When I finally met him, he was truly a nice and friendly person. I had my oil changed, spark plugs replaced and fuel filter replaced for $400 bucks. I of course brought in my own parts but it is still much more cost effective than bringing it in to the dealerships. I also had the air-bag light on becuase of the faulty wiring that comes with the 1999 boxsters. He used his durametric tool to turn that off for me for FREE! What a nice chap! I will surely go to him from now on for my Boxsters needs. I also recently moved to MD from Texas and have been looking high-and-low for a competent porsche mechanic.
