In 1970, this Corvette Roadster was built by Henry Gomez, Roy Boone, Darwin Bosell, and John Biza, owner of John's Corvette Shop in St Paul Park, Minnesota. In 1971, owner/driver John Biza began racing his newly completed Corvette Roadster. John held wheel-to-wheel competition licenses in F.I.A., I.M.S.A., and S.C.C.A. (S.C.C.A. Car Log book #18-335 car #12). John competed in many regional and national Trans-Am races such as, the Un-Cola Nationals, Pepsi Trans-Arn Nationals, and 7-UP S.C.C.A. Trans-American Championship. During his time behind the wheel in the 70's, his competitors included drivers like Hurley Haywood and Greg Pickett.

In 1976, the Corvette was purchased by Darwin Bosell, of Cedar, Minnesota. Darwin, a former crew member of John's Corvette Shop Racing Team, also competed in S.C.C.A. Trans-Am and Camel GT I.M.S.A. Series, Car #25. During this period, the Corvette underwent a transformation to make it more competitive in the ever-progressing racing world. In 1978, the car was rebodied into a hardtop/couple configuration with the 1978 Corvette Pace Car paint scheme, and was no longer a roadster.

With the popularity of the sport at or near its pinnacle, Darwin competed against a long list ofwell accomplished world famous drivers; such as, Paul Newman, David Hobbs, Rick Mears, Lynn St.James, and Willy T. Ribbs, just to name a few. The car raced with Darwin at the controls from 1976 to 1989 with many top finishes to his acclaim. This was a respectable accomplishment considering the factory and corporate involvement in the sport during the periood; i.e., Paul Newman and the Datsun/Coca-Cola Racing Team. In 1989, Darwin retired the car, and it was placed in storage. Accompanying photos show the car as campaigned by Biza in 1972 and 1975 and in 1984 with IMSA GT bodywork as campaigned by Bosell.

In 1994, Jack Beckman, also from Minnesota, purchased the old I.M.S.A car. With the help of Darwin Bosell, old photographs, and the original body parts, Jack was able to return the racecar to a roadster. Jack raced the car in many vintage events sanctioned by V.S.C.D.A., V.S.C.R., and R.M.V.R. After five years ofvintage racing, Jack sold the 1970 Corvette Roadster to the current owners in December of 1999. The car was then completely disassembled, the frame was checked for straightness and painted, and the original G.M. J-56 brake system was located and installed.

In 2001 it received the S. V .R.A medallion as a certified historic race car and has been running vintage race events with S. V.R.A., V.S.C.D.A. and Midwestern Council of Sports Car Clubs since April 2000. The dash board and fire wall are signed by former driver Darwin Bosell.
