Sorry, but that perspective is inaccurate. Carol was involved
in the design of the 2013 GT500. Likewise he pursued his passion in design by being involved with the initial design of the Viper which brought back many elements of the original Cobra. The same thing when he started his own manufacturing of the Shelby branded car. They have a tribute up to him at www.ShelbyAutos.com
which talks about his involvement right up until his death.
