in all reality neither car could do what they did in the movies without a lot of modifications and stunt drivers
Nah.. they just trashed them and moved on to the next one.
Although the estimated number of General Lees used varies from different sources, according to Ben Jones ("Cooter" in the show), as well as builders involved with the show, 256
General Lees were used to film the series. Others claim about 321
were used in the series. Approximately seventeen still exist in various states of repair. On average, more than one General Lee was used up per show.
When filming a jump, anywhere from 500 to 1,000 pounds of sand bags or concrete ballast was placed in the trunk to prevent the car from nosing over. Later in the series the mechanics would raise the front end of the car to keep it from scraping against the ramp causing it to lose speed, thereby providing a cushion for the driver upon landing. Stunt drivers report enjoying the flights but hating the landings. Despite the ballast, the landing attitude of the car was somewhat unpredictable, resulting in moderate to extremely violent forces, depending on how it landed. On many of the jumps the cars bent upon impact. All cars used in large jumps were immediately retired due to structural damage.
From 1979 to 1985, 1968 and 1969 model-year Chargers were sourced and converted to General Lee specifications. Despite popular belief, no 1970 models were used, according to all builders involved over the years. Obtaining cars was not a problem until later years. By that time, the car was the star of the show and Warner Brothers moved building of the cars in house to keep the cars consistent in appearance. Later in the show's run, when it got too hard and/or expensive to continue procuring more Chargers, the producers started using more 'jump footage' from previous episodes. In the final season radio-controlled miniatures were occasionally used to the chagrin of several cast members.
