Ardex was originally founded in France in 1934 but by the time war broke out in 1939, production stopped. But in 1952, it sprang back up out of nowhere, producing two (as seen here) or four seat microcars using single-cylinder engines of 100cc or 125cc. Production lasted until 1955 and only a few were built. This one should sell for between $15,000-$25,000. Click here for more info.
Update: Sold $13,800.
