This is the last Corvette ZO6 of several prepared by Marsh Racing that Whelen backed in the Grand Am and SCCA pro World Challenge Series. When Grand Am took over ALMS via merger, Whelen Racing moved up to Daytona Prototypes because Chevrolet had granted Pratt & Miller the exclusive right to race GT Corvettes.  Whelen GT Corvettes are a treasure if they become available for club racing, track days and the like.  More info: http://registryofcorvetteracecars.com/ee/index.php/site/view_cars/949
