Prolific Corvette buyer and seller Terry Michaelis of Proteam recently listed these three highly collectible Corvettes on his blog tMichaelis Corvette Perspective. The three cars, a 1963 Corvette Coupe, a 1968 T-Top Corvette and a 1970 Converitible, would be coveted by any collector, yet Terry's cars always seem to have that extra bit of provenance that pushes them to the top.
