A lot of cars were crashed during production. Replacing the police sedans was easy, but replacing the "General Lee" was much harder because Dodge stopped making the Charger. It got to the point where if producers saw a Charger on the street they would approach the owner and offer to buy it on the spot.
Ben Jones (Cooter) actually owns a small chain of stores called "Cooters Place" in Pigeon Forge and Nashville, Tennessee, and Luray, Virginia, dedicated to all things related to the show.
Waylon Jennings provided the voice of "The Balladeer," the off-screen narrator of each episode. He also sang the show's theme song, "The Good Old Boys", which became a hit single record in 1981. In the single version, there is an additional lyric at the end of the song: "You know my mama loves me... But she don't understand, they keep a-showing my hands, and not my face on TV!" This refers to the fact that it is indeed Waylon Jennings' hands playing the guitar in the opening credits, while his face is not shown. Jennings' mother had complained to him that she watched the show regularly, waiting for her son to appear, but he never did. This was finally remedied in Season 7, when Jennings made a guest star appearance as himself in the episode, Welcome, Waylon Jennings (1984).
The General Lee's famous "Dixie" horn wasn't originally planned; when the producers were driving in Atlanta during the first few episodes, they heard a car pass with a "Dixie" horn and chased the driver down and convinced him to sell the horn. They later realized that it was a novelty horn which could be purchased at any auto parts store for a third of what they paid for it. The horn was only used in the first five episodes. Once filming moved to the Warner Brothers lot, the horn was edited in during post-production.
