John and Cindy Mackay sent an update that they have recently celebrated 24 seasons of driving their Factory Five Roadster! Powered by a 480 HP LS3 engine with a Tremec TKO-600, they continue to put the miles on the Roadster having recently crossed the 25,000 mark! We're happy to see John and Cindy continue to enjoy their Roadster! #factoryfive #ffr #roadster #chevrolet #ls #lspower #customerbuild #customcar #classiccarsdaily #builtnotbought
