Gullwing America -- the same San Antonio operation that made asphalt waves with their modernized Mercedes 300SL Panamericana -- is back, and ready to build you a near-undetectable replica of the 1964-65 P/904 Carrera, a Le Mans-winning ride they resurrect by taking a 2nd-gen Boxster provided by the purchaser, cutting away the body, and throwing on their hand-built P/904 shell.
