Goggomobil, no e please, its German not American, Dart, styled by Stan Brown, from memory, ex- Lotus man, for Bill Buckle. You can see the vague image of the Lotus 11 in the lines. The drop down optional extra door sealing hereditary. Daimler and Dodge (GM) also used the name Dart leading to a tiff over that. From the rear the Dart retains its Goggo look as the lines, though lower, as matched and the Saloon parts from a knock down Dingolfing kit used from the standard production line. It is, in effect a stylistic alteration like a Fiat Jolly and the Chassis number does not immediately tell you what car type it is originally from. So exact numbers made are hard to know.
Another car in the Micro lists, but to my mind a light car, that manages to be a differently styled, but recognisable house style, at the same time, is the Citroen Bijou, from Slough. It has rather good lines and having had a few its a frustration it was never available with the later mechanics, nor has a replica been done. So I must be in the minority of liking this car.
