The History


Back in 1969 at age 13, owner Joe Cogbill was introduced to Porsche racing by his father and in 1979 Joe began his racing career with a 1959 Porsche Speedster. Only 2 years later in 1981, Joe finished second at the Atlanta Runoffs to another Speedster driven by John O'Steen. The following year in 1982, Joe claimed his first SCCA Runoffs national championship. And the rest was history.
