By complete coincidence I was reading about the Moretti 750 Gran Sport from the mid '50s just the other day. This is rather later when they stopped making their own engines and focussed on special bodies FIATs. This one is a FIAT Moretti Sportiva 850 from the mid to late '60s.
I think it was earlier in the thread, but yesterday I actually saw an Austin Maxi 1750 being driven up the M5 by an old girl. I've not seen one in the flesh for decades. It was in that lovely BM khaki brown too. Also saw an Anglia in the services
