These guys are good!!! Callas Rennsport, specializes in BMW, Porsche repair and maintenance. The service they do on your automobile is high quality. Done by a team with proper training and a lot of experience, Callas Rennsport delivers complete customer satisfaction.My most recent experience, I took my car to a local Porsche service dealer and my car came back in a worse condition than when it came in. My Porsche was dripping liquid perhaps leading to my steering giving out. The dealership said I needed new brakes when a week prior I got brand new brakes from Callas Rennsport. When service is done at a dealership, you don't know who is working on your vehicle. You don't know if these guys have certification at all. If ever you're in need of service for any series BMW or Porsche, come to Callas Rennsport. They're a great team and they are very knowledgeable.
