Here’s what Randy Leffingwell has to say:
Motorbooks International, the car books publisher, asks me every few years to write or update the Porsche 911 Buyer’s Guide. These are the guys I come to first for advice, insight, and information. They have seen everything and they know the cures.
Here’s what Paul Conquest has to say:
“Tony Callas is a true jewel. I first met Tony when he came to Edmonton in his role as a Porsche technical trainer with Worldpac Training Institute. Trainers need to know their subject cold, and it is an understatement to say that Tony is an exceptional trainer. However, what impressed me most was not his incredible wealth of knowledge on Porsche, but that he was willing to share this knowledge with others to help make our industry stronger. In the years since Tony first came to Edmonton I have visited Callas Rennsport and met Tony’s staff several times. What impresses me is that without exception the staff at Callas Rennsport share Tony’s desire to make the right diagnosis, to pay attention to the details, and to treat customers fairly. If I lived in the South Bay area, I would take my Porsche or BMW to Callas Rennsport.”
