A 1929 Rolls-Royce 40/50hp Phantom II Weymann Sports Saloon, reputedly the last model that the marque’s co-founder Henry Royce designed himself, is one of the highlights of the Collectors’ Motor Cars and Automobilia sale atÂ in Oxford, UK on March 5th. The rare vehicle is expected to fetch up to $325,000. The now legendary Phantom II chassis provided a platform for some of the truly outstanding designs of its day, and was highly favored by prominent coachbuilders. The example offered by Bonhams carries Weymann-type sports saloon coachwork by the famed firm of H J Mulliner. It’s presented in perfect condition having undergone a complete restoration and is perfectly capable of high speed road trips and classic car rallies.
