Apparently.... when filming the Dukes of Hazzard they got through a several Dodge Chargers per episode.... none would survive the classic car jump scenes - a requisite in almost every episode
and had at least 2 for close up shots and one for the trailer for "moving" shots. So which would count as the original ?
Though Daisy didn't need a stunt pair of "Daisy Dukes" (ask yer dad !)
In Mad Men there were x2 1962 cadillac coupe de ville - again one for trailer shots - other for close up static shots
So maybe its only shows like Morse where you could say for sure its the one Jag used in the show
