For the past 35 years I have owned a 1986 911 Turbo (930) Porsche, which I bought new. I have enjoyed an amazing relationship with Tony Callas of Callas-Rennsport over the last 22 years, during which time he handled all maintenance and engine upgrades my 1986 911 Turbo exclusively. Before that (after the new car warranty expired), the car was cared for by Edelweiss Porsche in Torrance, where Tony worked until setting off on his own and establishing Callas Rennsport, also in Torrance. Tony has established himself among the elite of Porsche mechanics and from time-to-time works with different Porsche racing teams. His associate, Tom Prine, is incredibly knowledgeable about everything Porsche and willingly shares his wisdom and enthusiasm. David, the service manager, is excellent, and the repair and maintenance technicians I have had the pleasure of dealing with are, in my opinion, top-notch. Everything they have repaired on my car has proven to be reliable. I feel that they treat my car as of it were theirs. If you want the highest quality treatment for your prized possession, I honestly don't think you can do better. I wish I could give them 6 stars.
