Mercedes-Benz introduced the 230 SL roadster in 1963 with distinctive concave roofline that earned the nickname "pagoda top." Built from 1963 through 1971 on the W113 platform, it featured a low waistline, large curved greenhouse windows, detachable hardtop, and a new 2.3-liter six-cylinder inline engine. This surviver, perhaps undergoing restoration, was found in Black Creek, N.C. (Photo by Jim Meachen)
