Mopars, specifically, E-Bodies, have paid their dues and to me I think that equates to respect by car/Mopar enthusiasts. Unlike modern cars, they aren't remaking these vehicles any more and they aren't around every corner. Some Vipers and alike aren't being manufactured any more either but they are still reasonably new in terms of years since build date. When Vipers, LX Challengers, etc reach 40 years old, then you may see a little more respect and a following for them and more "anger" or "feeling" towards someone who wants to chop them up.
Me, personally, I'm all for customizing these cars but hate seeing it when people chop, hack and DESTROY these cars to a point of no return. When they hit that point, there is no going back for them or any future buyer(s). Neons in the truck, 18" rims, subwoofers and non-factory paint is one thing, cutting the back end in half, chopping the roof line and welding half of the Titanic in place is another. At the end of the day, you'll get the "It's your car, do what you want....blah, blah, blah" but when there are limited numbers remaining, it sometimes pays to think for the cars sake, not yours. If the car is an absolute mess and needs all sheetmetal replaced, no drive train, to me, that is fine to go wild with, it's either that or rot in peace.
Good question.
