Aston Martin is widely expected to take the record for the most expensive British car at auction when this one-of-four DP215 prototype race car crosses the block at the Monterey Car Week. The DP215 is last race car made by the Aston Martin factory and was designed to compete at Le Mans. Clocked at 198.6 MPH, the DP215 broke the top speed record at the track and looked to be a sure winner, but a gearbox failure forced the car to retire after only two hours. The DP215 has undergone a multiple-decade restoration, including a new transmission made from the original plans, as no others existed. With its history and Aston Martin pedigree, the DP215 is one of the most important British cars ever made.
