Just been to a classic car show (Woodvale Rally), and got talking to a guy who worked for a car importer who imported various makes of cars to the U.A.E. Turns out he says a hangar on the old R.A.F. base at Sharjah was used for storing the cars and recalls in 1982-83 there were 19 DMCs unsold within it, all were unpainted and apparently cannibalised for spares for unknown reasons. Can't vouch for the validity of the story but he has pictures of some of the DMCs, I've given him my email adress so hopefully some info may come of it-fingers crossed!
