RM’s Scottsdale Auction just got a whole lot better. At the forefront of the new announcements is this Cobra prototype which was the first fitted with a 427 and the only one with a flip-top front-end. It has been extensively campaigned in modern historic events and is ready to hit the track.

Another big announcement is a Chrysler Thunderbolt concept from 1941. This was one of Chrysler’s very first show cars, described at the time as the car of the future. This particular example was shown at Amelia Island and Pebble Beach this year in its fabulous hue of green with brass accents. It complements the 1954 Mercury Monterey XM-800 also at the sale.
