I have never had one, but I have seen them. First off, it was engineered by Pyro Plastics in the mid 1950's. It has a generally crude, multi pieced body (predated the multi-piece sliding insert molds pioneered by George Toteff of AMT models.) That said, as far as Auburn Speedsters go, I think it is the only game in town. Highly accurate it isn't, but it's still kind of neat.
It's for the shelf, not for actual driving. You don't need to fit into it. Pretty sure that Actually fitting into the car in scale was going to be a concern, they wouldn't have reissued it. In other news, I got me a "Catch the Kat" issue last night molded in metal flake blue.
