The Austin-Healey 100 was that British roadster with a four-cylinder engine, plug-in windows and minimal comfort, wasn't it? Yes, but there were exceptions, one of which was built in Belgium and was a coupé. Presented at the 1955 Brussels Motor Show, it was the prototype for a series of six cars, two of which have survived. This report is about the show car, tells its story and shows it in many pictures.
