Universally recognized as the most unique and valuable postwar
Bentley/Rolls Royce in existence, the 1947 Bentley Mark VI Cabriolet, with custom coachworks by French coachbuilder Franay, is heading back to the Barrett-Jackson's auction block next month where it is expected to be sold for around $2 million. Five years ago the car was sold for $1.76 million at the Palm Beach Collector Car Event, and its value has estimated to have increased by up to 25% since.
