Bugatti Type 57sc Atlantic Coupé, 1935. Designed by by Jean Bugatti, son of founder Ettore, the Atlantic Coupé was based on the Aérolithe concept which used Elektron (a magnesium alloy) and Duralumin (an aluminium alloy) for its body panels. Therefore, the body panels were riveted externally, creating the signature seam. The production Atlantics used plain aluminium, but the dorsal seams were retained for style. Only 4 Atlantic coupés were every made, of which 2 have survived to the present day. Most recently one was sold for a sum believed to be $40 million
