Chevrolet Dealer and noted Corvette Collector Bob McDorman will be bringing 25 unique cars to Dana Mecum's Spring Classic in Indianapolis in mid-May. Among those cars is the first true high-performance Corvette in history, the 1954 EX87 test mule that Corvette's first Chief Engineer Zora Arkus-Duntov drove to 163 mph at the Arizona Proving Grounds.
