When we were young my brother had a book about cars and there was a picture of an unusual car, perhaps from around the 1930s, which looked a bit like a Rumpler, Crossley-Burney Streamliner or more old-fashioned version of Fiat Multipla/BMW 600.
I remember it being called the Hotchkiss Multiplex but I cannot find any reference to it on-line. Perhaps it was a concept which never materialised, or a special body made for a chassis, perhaps the book's writer was wrong or perhaps I am mistaken.
Anyway, if anyone has/can find a picture or info I would be really grateful. Not important, purely curiosity!
