We’re looking here at one of the rarest cars Aston Martin has ever produced, with this particular prototype of the exquisite DB4GT getting ready to cross the auction block at RM Sotheby’s upcoming Pebble Beach event.

[Update: With the hammer having dropped, the stunning and unique Aston Martin DB4GT prototype fetched $6,765,000 following heating competition that included three suitors. It’s well within the range of the early estimates, albeit at the low end of the deal. The DB4GT was actually in the top ten expensive products – turning up sixth at the Saturday event.]

As a matter of fact, being a prototype of the stunning DB4GT, this example us unique in the world, meaning the estimates are just about right when claiming it will fetch up to $8 million. This one-off Aston Martin was the work of Harold Beach and Ted Cutting, and their work came after the DB4 was introduced during the Paris Motor Show – they had to cut “five inches out of a DB4,” and deliver “a cheap and cheerful GT car.” The result was the DB4GT prototype seen here, which was introduced in March, 1959. DB199, as is known now, had a 93 inches wheelbase, with the back seats deleted in favor of a luggage platform. Power came from the original 3.7-liter straight-six engine packing a punch at 280 horsepower (208 kilowatts).

Brand new, it was crowned as England’s fastest passenger sports car, with a debuting victory at Silverstone with Sir Stirling Moss at the controls. The sports car remained quite successful during its motorsport career, and when retired it became a press and development car. It had several owners and in 1989 a commissioned restoration. It’s still in original condition, and will be part of RM Sotheby’s Monterey auction, kicking off on August 18.
