I would think a lot of the early Ferraris would qualify, since the street
cars were just an afterthought and the engine development was concentrated
on the race cars.
As a wild guess (I'm a little foggy on pre-war MG history), how about the MG
K3? Was that little 6cyl based on a Morris motor, or was it an MG original?
I suppose you could argue that it wasn't really a street car...
