Bonhams will present an extraordinary collection of cars for auction as part of the Goodwood Festival of Speed Sale on June 26.

1961 Porsche RS61

The incontestable crown jewel of this auction is this Porsche RS61 being sold by Sir Stirling Moss. This car is the last one the legendary Formula 1 racing driver, described as "the greatest driver never to win the World Championship," ever raced, and he describes it as "the best car you could buy."
Valued at $2.6 to $3 million

1935 Aston Martin Ulster Competition Sports
The hammer won't come down for less than 2 million euros for this sensational Aston Martin, a veteran of the Le Mans 24-hour, the Mille Miglia and the 1936 French Grand Prix, where it was driven by the brilliant Dick Seaman.
Valued at $2.4 to $3.3 million

1958 Mercedes 300SL
This cabriolet version of the famous Mercedes 300SL, the fastest production car of its day, is often seen on the auction block. In six years of production, only 1,858 of these luxurious sports cars came off the line.
Valued at $1.2 to $1.5 million

1954 Jaguar XK120 Roadster

1961 Rolls-Royce Silver Cloud
