One of the last 2 GT1 cars built by Pratt & Miller.  Retired after it won at Le Mans in 2009 because the team believed more competition was needed to stay relevant and switched to GT2.  Sold to collector completely original after Le Mans.  Conditions forced sale to another collector in 2016.  More info: http://registryofcorvetteracecars.com/ee/index.php/site/view_cars/511
