Six historic Ford Performance race cars worth several million dollars each will be crossing the auction block in late August at an event hosted by Chatham, Ontario-headquartered RM Sotheby's.

The six cars from the Jim Click Ford Performance Collection make up the first lots RM Sotheby's has listed for offer at its popular Monterey, California sale, the flagship auction held August 19 and 20 during the renowned Pebble Beach Concours d'Elegance.

Click, who owns 16 car dealerships in California and Arizona, is downsizing the collection of Ford performance vehicles he's been racing at historic motorsport events since 1991.

Among the vehicles he's offering for sale is a 1964 Shelby 289 Cobra, chassis CSX 2473, one of the most successful 289 Competition Cobras of all time. Former owner Don Roberts netted close to two dozen first-place trophies with the car between 1966 and 1984, and also maintained the car during its tenure under Click's ownership. It's expected to fetch $2.2 million to $2.6 million.

Also for sale is a 1966 Ford GT40 Mk I, one of 31 Mk I road cars produced, and a car formerly used by Ford for promotional purposes. The car, which Click has owned and raced since 1992, should return $3.75 million to $4.25 million.

Another '64 Shelby Cobra 289, estimated at $1 million to $1.4 million, complements the Roberts-raced car, as does a Roberts-prepped SCCA-spec 1966 Shelby Mustang GT350 racer, which Click is selling at no reserve. The car should return $350,000 to $450,000, RM Sotheby's believes. 

The sale is rounded out by two Ford Mustang Boss 302 Trans Am racers from 1969 and 1970, the former campaigned by the Shelby team with Dan Gurney at the wheel, among other drivers; and the latter by the Bud Moore team. They should return $1,000,000 to $1.3 million each.
