impact of modern muscle cars on the old car market

Having owned both and being a "young" guy (at least I hope I can still call myself that at 31) I don't think modern muscle is impacting old muscle. I've had a 71 Duster, 69 Dart, 70 Cuda, and now my 68 Dart. For new "muscle" I've had over a dozen twin turbo Dodge Stealths, Dakota RT, and a 300C SRT8. None of them gave me the feeling that my old musclecars give me. Plus as an added bonus I get compliments all the time in my old cars and rarely get noticed in my newer muscle. As a daily driver I enjoy a modern musclecar but going to a show with one is just boring imo.
