There are a few D reg cars where they sat unsold for a long period. Reality is that the bubblecar period was pretty short really. Watching films they appear in the street scenes, sometimes as major props, from about '55. Soon they a relegated to being in the background. By '65 they rarely appear even in street scenes. I re-watched Lindsey Anderson's 'If' recently. Partly as it was to be filmed at our school till the plot was discovered. The school regime it depicts was only partially unravelled when I went to school. It could be pretty barbaric. Anyway, in the bit where they cope off school and nick a motorcycle, there in the road is an Isetta. That was 1967, film released in 1968. Not sure where that was filmed. It might have been Bristol. The school location ebnded up at Cambridge so much was shot over there. Such was the budget that old footage could not be thrown away though. They could not even afford to film entirely in colour! So it chops from colour to black and white.
I know where the dealers were for microcars round here. I cannot recall any with new stock. Some put through trade ins. In Oxford the trade diverted to Eynsham as Basil set up as an independent. It was on the back of him that Waste did bubblecars, stealing his business, and good name, by having a better position on a main road. It was Waste who had a Peel and other goodies in the yard, later rescued, as he was not a pleseant guy. He scrapped a huge pile of engines rather than sell them off. Many of the cars there died too.
