The Monaco King Cobra is a remarkable piece of history, built by Carroll Shelby and the Shelby American team to race in the first year of the USRRC (United States Road Racing Championship). This was an eight-race series with both prototype and GT classes, similar to today’s IMSA series. Driven that year by Ken Miles, the King Cobra was no stranger to the winner’s circle. The King Cobra was also the forefather of the Ford GT40, since it was a development vehicle for that program. With a screaming 289 V8 pushing out 400 hp and a chassis that weighs a little more than a bag of feathers to go with that racing provenance, it’s no wonder it sold for $1.65 million at Barrett-Jackson in 2014.
