Yes, the dealership was on E. main. By the 70's the dealership had been sold to Bill Koch (I think that is the spelling for his last name).
Originally the dealership was started by Claude Gains and HJ Meyer. Fortunately, Don Sesslar came into the dealership in 1960 and suggested they start racing an Alpine. Don, who was better known at the time for winning the F-M championship in a Porsche RSK, was a real asset and they had very good success with the Alpine. Eventually Don started running the Tiger.
Of course they were winning with the Alpine. So a relationship built up with the execs. at Rootes and support developed, too.
HJ Meyer saved everything from the days they were racing the Alpine and Tiger. Down to the copies of the travel reimbursment checks.
On the west coast Hollywood Sport Car enjoyed similar support.
