I don't recall seeing a real breadvan looking similar. Is there a story here?
When I was a kid the Co-op bread van had a short hatchback type window opening through which the delivery man would remove the loaves from a head height shelf. If I Google "breadvan" most of the images I get are of the Ferrari 250 GTO, and the back of that looks very much like the breadvans I remember.
I've never heard it applied to the Europa though.
