25 years ago I'm sure a new car in stock at a Morgan dealer did not happen that often, maybe a cancelled order from time to time.
The Scottish dealer in Burrleton in Perthshire did not have any new cars in stock in the early ninties when I went in.
Is there a rough date that production demand changed and it was possible to get a selection of cars from stock by checking a few dealers.
A wild guess on my part, say from 2010 but just a guess.
