There Were 17 General Lees Left
When production of the final season wrapped up, there were 17 authentic General Lees that were left behind. The cars were in various stages of disrepair and a few of them were pretty much junk. The relevant survivors were eventually sold at auction and a few of them have been restored. The car itself was one of the most popular body styles of the Dodge Charger (via Hot Cars).
Because the cars were involved in various stunts there was a lot of damage that was done. The cars were sent flying in the air, on high-speed chases, and a variety of other damaging stunts. None of which were what the car was natively built for. Nevertheless, the Charger was an admirable choice for the show.
