In 1954 carmaker Borgward launched its most popular model: the Isabella. Founder Carl Borgward had the sedan converted into a slick coupe specially for his wife. The latter caused such a commotion that the Borgward Isabella Coupé went into volume production in 1957.

The result was a very exclusive affair, as only two dozen convertibles based on the Isabella coupé were built. Drive it! discovered one of these rare specimens.
