impact of modern muscle cars on the old car market

I've wanted a new Challenger since they came out. I think they are awesome. The biggest drawback is any parts to modify a new car is insane. I read an article about installing headers, and exhaust. It also required a custom tune. By the time it was all done, it was 3 grand. I ended up buying a 13 Ram truck instead of the Challenger. It's a more useful vehicle, and I love that truck. But as mentioned, the service departments suck dog balls. The aggravation and lies I got from them were astounding. Now I look at my Dart, or my Sport Fury, and they make me smile. And they get plenty of attention. And I can work on them. So I wonder sometimes if I should sell them, and get a new Challenger. Then I think about the above reasons, plus, I don't want to be one of those guys that can't work on their own stuff. So, does it affect the classic car hobby? I say yes. You get a bunch of know nothings filling up the car shows, getting a trophy for something they pay for to have, and to have worked on.
