Callas installed the Clewett serpentine belt system, along with some other maintenance work, on my 993. Andy was the technician. He was meticulous and treated my car like his own. Everything turned out perfect and my car ran better than when I brought it in due to Andy’s expertise, caring and attention to detail. David kept me up-to-date with pics every step of the way. Callas isn’t the cheapest shop but they’re the best in L.A!
