One of the bad things about the originals is that some of the dimensions were off from the first two
as "Luigi and Guido" misinterpreted the blue prints so the last 4 weren't exactly like the first two,
story has it that the first two were the same the second two were identical to each other and the last
two were identical to each other and the there was the John Wilment coupe also.
Just some food for thought
