Mecum Auction House is selling a twofer 1969 Chevrolet Corvette L88 at its Glendale, AZ auction this Saturday, March 14. Pre-estimates for 1967 L88s, can command well over $1m, the rarest Corvette, with just 20 made. The more “common” 1968-1969 models draw less impressive sums, but remain a powerful draw for collectors.
