SCCA legend Don Roberts has driven plenty of cars, so to call this 1964 Shelby 289 Cobra his "favorite" might be a stretch. That said, there's little doubt it's special. After being originally purchased and upgraded to competition spec by one of Shelby's own employees, the car was sold to Roberts, who piloted it to a win in its debut outing before converting it from A- to B-production specification. Over the next decade, he would win three SCCA Divisional Championships behind the wheel, and after a second spell in ownership, re-acquired the car in 1980 and then piloted it to four straight Monterey Historics wins. Even though the car is now with a different owner, Roberts still does maintenance on it, and might very well be on hand to see it auctioned at the site of so many of its successes.
