Carroll Shelby entered two turbine cars in the 1968 Indianapolis 500. They were designed by the same guy that did the STP turbine for 1967 and looked very similar. Ultimately the cars were withdrawn before they attempted to qualify because they were found to be illegal. The cars were sold at auction years ago and are now in private hands. There was a small article in HOT ROD about one of them. Anyone know where they are now? Thanks!
