I don't pretend to know everything about my 911, so I'm appreciative for places like Callas Rennsport. I trust Tony and team above any other for routine maintenance, any mechanical issues or if I just need some Porsche-related advice. They were the first call I made after being rear-ended on the freeway. The team always goes above and beyond what's required. It doesn't matter if one drives a multimillion dollar collector or a multi-accident everyday driver. The team spends the time to explain what they're working and many of the details behind the work. Tony is never too busy to great you upon arrival, even if he's in the midst of working. The amount of knowledge and meticulous work is amazing. Between Tony & Tom and the rest of the team, it's hard to find more knowledgeable, genuinely great people, that share the same passion for Porsche.
