I had Tech inspections for the track and the IMS replaced on THAT at Rennsport Werkstatt in Tulsa. They took good care of the cars and were a pleasure to deal with.

I will take my cars there again without hesitation.
I bought this car at Tom Charlesworth Inc. After I decided to buy it and he had a moment to chat, it was hard to break away. He has been a Porsche enthusiast forever. I got the impression that he is more specialized in the old-school Porsches and his shop had some nice ones being worked on. I would not hesitate to use him, but I would expect that some of his long-time customers may take priority.
