For 40 years, the 1968 Mustang GT fastback that starred alongside Steve McQueen in Bullitt – arguably one of the most iconic movie cars ever – was thought to be lost. That is until now. Despite the best efforts of McQueen, who himself attempted several times to purchase the vehicle back in 1977, the original Mustang belonged in the private collection of Bob Kiernan, an insurance executive who planned to restore the car with his son, Sean. But when Kiernan succumbed to Parkinson's, Sean finally revealed it to the world. Photos by Casey Maxon.
