Why it matters

The 375 C was the open-top derivative of Peter Monteverdi's High Speed 375 S grand tourer, the Swiss firm's attempt to add a convertible to its Chrysler-powered range. Only two were made, and one of them was later reworked into the Palm Beach, which makes the unaltered cabriolet one of the scarcest Monteverdi road cars.

Independent counts (e.g. engine and colour) are never combined into a calculated figure. Surviving examples are never presented as original production.

History

Monteverdi launched the High Speed 375 S, styled with Pietro Frua and powered by a 7.2-litre Chrysler V8, at Frankfurt in September 1967. A convertible version of the 375 S followed and was shown at the Geneva Salon in spring 1971 as the 375 C. Just two cabriolets were built, and one of them was subsequently modified into the Monteverdi Palm Beach, leaving a single surviving 375 C in its original form.
