In 1968, a Ford Mustang GT drove up San Francisco streets and across movie screens in the iconic Steve McQueen film “Bullitt.” Today, one of the two Mustangs used in the film, dubbed the Ford Mustang Bullitt, crossed the auction block at a Mecum Auctions event in Kissimmee, Florida selling for $3.4 million.

Its sale price makes the sports car, colloquially known Bullitt Mustang, the most expensive Mustang sold at auction to date. The car originally sold for $3,500.

For decades, it was thought that the original Mustangs used in the movie was lost to the annals of history. They weren’t.

One was sent to a salvage yard and then resurfaced in 2017 in Baja, California. The other was purchased by a private buyer.

Instead of living it’s best Hollywood life, the second Mustang was actually doing duty as a daily driver for the Kiernan family. McQueen tried to buy the Mustang from the family on numerous occasions but was rebuffed each time.

Instead of being driven by McQueen, the car wracked up 65,055 miles on its odometer as a daily driver and then was parked in 1981. The decades since we not kind to the car, which sat in a growing state of disrepair.

It was the Kiernan’s son, Sean, who brought the Mustang to auction. He inherited the car in 2014 and began to work with Ford on plans to clean up and show off the model.

Now, the Mustang’s time with the Kiernan family has come to an end. The identity of the buyer has not been revealed.
