This 1958 Porsche 356A T2 1600 Speedster, chassis 83818, was assembled at the Zuffenhausen factory in October 1957 and dispatched to the North American market via the Max Hoffman agency. It gained a notable competition record in SCCA E-Production racing during the 1970s and 1980s, earning back-to-back regional championships in 1978 and 1979, holding the Road Atlanta E Production lap record for a decade, and being recognised by Porsche Panorama as the world's fastest Speedster. A comprehensive bare-metal restoration was subsequently completed in California, returning the car to factory specification in Ruby Red over Beige leather.
