So when did you last see a Triumph Herald courier van on the road? It's been such a long time that we'd actually forgotten they ever existed. Has anybody got any clue how many have surived?
And here's another oddity - a Dodge van. I guess this was based on the Simca 1100. If memory serves they made a hi-cube van and a pickup too. All three are slightly rarer than rocking horse manure these days.

Ah, the Triumph Courier van! And they always seemed to be either battleship grey or sage green! Anyway, Canley Classics
(http://www.canleyclassics.com/triumphmuseum.asp?article=ga154173v.xml) have four, but Standard Triumph couldn't even sell them when they were new, so production was very soon stopped.
I'm sure I've read that the total number of survivors is no more than about 20.
I got one, yes they are quite rare, I believe they have about 6 in Norway too
