Now in its 14th year, the Bonhams automotive sale at Quail Lodge is the longest running auction during the most famous collector car event in the world – Pebble Beach Car Week. This year Bonhams was selected to represent the Solomon R. Guggenheim Museum’s singular 1979 BMW M1 Pro Car painted by Frank Stella. This is the only BMW car ever painted by an authorized BMW Art Car artist for a private client and, therefore, is totally unique from the 16 official Art Cars commissioned to date by BMW. In addition to being a rare and beautiful example of popular culture and automotive art, this M1 is also purpose-built for performance and is a true race car.

Bonhams was also selected to represent the ultra-rare 1954 AJS E95 “Porcupine” at its renowned August automotive sale in Carmel. One of just four E95s completed by the factory, the Porcupine (so nicknamed because of the spiked cooling fins on its cylinder head) was created as a works racer by British manufacturer AJS and is perhaps one of the most legendary motorcycles in history owing to its brief, sunburst racing success and extreme rarity.
