Joe, I used to drive a Ford Transit van, in fact I drove it from Melbourne to Perth.
Obviously your transit is something else.
Would you please explain.
Read the joke, scrolled down to the Wikipedia link, saw the picture, re-read the joke. Now I get it
For me, as Mike said, a Transit is a Ford van - "the backbone of Britain" as the advert used to say. Until they closed the factory and moved production to Turkey of course. Small fact to bring us almost on-topic, the Ford Transit factory used to be the Cunliffe Owen aircraft factory and was only cut off from Southampton Airport by the building of the M27 motorway in the early 1980s. The flight test hangar from which K5054, the very first Supermarine Spitfire emerged was also part of the site and survived the closure and demolition of the Ford plant, although appears to have been re-clad in rather non-period corrugated metal panels according to the latest Google imagery.
