Considering Danny and Baez often have to track down killers on "Blue Bloods," investigating the disappearance of a movie prop was probably a nice change of pace. Danny even refers to it as the "Mona Lisa of cars," and he's not wrong. Given the fact "Bullitt" has one of the greatest car chases of all time, the real Mustang would certainly be worth a pretty penny. So where is the car in real life?
There were actually two identical Mustangs used for filming "Bullitt." A man by the name of Robert Kiernan purchased the vehicle in the 1970s, holding onto it for decades. Even a passionate letter from Steve McQueen himself wasn't enough to get him to sell it. Kiernan passed away in 2014, and the car was later sold at an auction in 2020 to the tune of $3.4 million. With that kind of cash on the line, it's no wonder Anthony Edwards' "Blue Bloods" character attempted to get some kind of payout from it.
As for the other "Bullitt" car, it went missing for quite a while. The second vehicle was the "stunt" car that took more of a beating during filming. The damaged car eventually wound up in a scrapyard in Mexico, and it wasn't until 2017 that its cinematic origins came to light. According to prior reports, the car's now owned by Hugo Sanchez (who bought the car from the junkyard) and Ralph Garcia (who owns a custom shop the "Bullitt" car was brought to). They were still working on restoring it as of the last update, but maybe one day, it'll be seen on the road once more.
