If we look at this from the devil's advocate prospective.....
Except for the 1960's Chevys, the cars they use are all just used cars, with little to no collector appeal. When was the last time you saw a frame-off restoration on a late '80's Cutlass Supreme or a Buick Regal? Or a Cadillac Fleetwood built on a Chevy Caprice chassis with a 307 "Y" motor in it? Or one of those old hideous Lincoln Town cars? They are messing up cars nobody else wants. Ones they can buy cheap. There was a video of some guy who had put $79,000 in a Cutlass, only to flop it onto its top the first time he tried to stand it on the rear bumper. The paint and chrome work on these cars is above reproach. I don't understand the demolition derby mentality at these "meets". The audience seems to enjoy it when something gets torn all to "deleted". Even the guys whose cars get damaged don't seem to get too excited. I saw a video where a car hopped onto another one, totaling them both. The owners of the two cars involved bumped knuckles and acted like the best of friends. The batteries and relays commonly get on fire and burn up the car. I saw a '64 Impala SS burn up due to an electrical fire that started in the trunk. All the lifting and "hopping" is done wth that contraption they put on the rear end of the car, best I can understand. How do they get the driveshaft to be happy running at that angle? You notice they don't drive the car with the rear end all jacked up. They call them lowriders, but they are all jacked up on hydraulics. I don't understand the thinking, don't enjoy seeing a car put thru such silliness and would never participate in such activities if I were at gunpoint. But, I respect almost anything that people put some of themselves and their ingenuity into, even though I might not attempt such an activity myself. I'm the last to know anything, so I was not aware that such a thing as this existed. My wife says I'm easily entertained.....

Life can be tough. It can be even tougher if you're stupid.....
