The best cars that were only built once

The best cars that were only built once revisits how early coachbuilding made single examples easier, before monocoque construction increased cost and complexity. It explains that today one-offs typically appear through customer commissions, marketing, or as concepts that never reach production. Several specific vehicles are cited, starting with the Peugeot 404 (1966), which began as a cabriolet before a diesel record attempt with a fixed narrow roof and 69 bhp; it ran for 72 hours at Montlhéry and broke 22 speed records. Ford’s Supervan 1 (1971) is described as a Transit Mk1 body hiding a GT40 chassis with a mid-mounted 5.0-litre V8, delivering 435 bhp and a claimed 0-100 mph time of 21.6 seconds, but it was scrapped in the 1970s. Other one-off examples mentioned include the Fiat 130 Familiare (1971) and Aston Martin Bulldog (1980) with a twin-turbo V8 rated at 700 bhp.
