The Goggomobil Dart was built by an Australian company called Buckle Motors. It was unique to Australia.
This Dart is very interesting. It's apparently a recently built car. Andy Carter runs a place called Andy's Modern Microcars. Andy's Modern Microcars builds microcar bodies that look just like the originals. Besides the Dart, he creates Messerschmitt, TG500 (Tiger),Isetta, Scootacar, Kleinschnittger F125, Peel Trident, Peel P50, Bamby and Mopetta bodies.
You can build one of Andy's microcars on "modern" floor pans, but the owner of this Dart chose to build his on a Goggomobil floor pan. He uses a 250cc Goggo engine and other Goggomobil parts. Best of all, it's LHD. (All original Goggomobil Darts were RHD.)
This is not my type of car, but it's an interesting recreation of a unique piece of automotive history.
