I have heard that there were 40 or so cars on the Dukes of Hazard set. Most were being repaired for the next jump.
I recall the story (believe you can Google it) in which one of the very first General Lee stunt cars used (the one featured in the opening theme sequence jumping over Roscoe in his patrol car) was discovered in a junkyard near where they shot the first few episodes in the Covington/Conyers, GA area. The vehicle was identified as such with the plastic labels inside the hood saying “WB-2” or something to that effect. Vehicle was restored and is a proud exhibit at Dukes of Hazzard shows around the United States.
