We had a Bond Minicar in the family when I was a kid. It had to be the soft top version because at 6' 4", Dad wouldn't fit in the hardtop.The brakes failed going down a steep hill and we had to run into the back of a parked A55 butchers van to stop. The Bond was a write off, the A55 had a broken reflector.
In my teens, the local RAF lads used to buy up any bubble cars, Isettas were favourites, they would use them for (non MSA!) racing on the airfield runways.
