I watched the film 2 Guns the other day, not a bad film and the 1970 Challeger 440 looks awesome. Except it turns out the car's actually a 1974 318 and was made to look like an earlier car. Still looks great though. And it was for sale a few years back for £14k! Wish I'd known, would have bought it in a heartbeat.
This is the ad for the car from a few years back.

If Bullitt is anything to go by, maybe with worth a few million in 50 years time, I'll be long gone though . . .
