A vehicle that impressed the car industry back in 1956, the BMW 503 cabriolet was the first one to feature an electric soft top as standard equipment. Its chassis was entirely made out of aluminum with its design not following any trends from abroad, entirely produced and designed at BMW.

It was the first coupe built by BMW after WWII and it was a disaster in financial terms. It was built before the 507 roadster, which was another financial loss for the struggled German car-maker.
