I recently got a very old plastic toy of the XK120 roadster, which is about 1/15-1/16 scale. While it's truly a toy with metal axles, a thing that passes for an engine block, hollow 1-sided tires/wheels, and is missing the dashboard, the body is amazingly accurate. It won't take much to turn it into a very nice curbside club racer like the one in this thread, using a few parts from the 1/16 Jaguar SS100, and the hand-lace wire wheels from the 1/16 Mercedes SS Sonder Kabriolet make it look awesome.
