Just saw this on Google looking for scratchbuild info. Longtime plastic modeler that's got into card stock models a few years ago. Primarily into antique, brass era stuff - cars, trucks, tractors, airplanes. The only sports car thing going right now is trying to modify the old Aurora Aston-Martin DB4 into closer to correct. If you count it at least as a sporty car, the really old Pyro Auburn Speedster 851 into a more accurate configuration using photos and some drawings from the old IAAM Bulletin.
