impact of modern muscle cars on the old car market

What I have noticed getting older is that if I cant do something right, I dont do it. I am restoring my Dart, but am not rushing it, it has to be dne once and done right because I am not going back over it twice. It is a combination of time, priorities, and that I am not young any more. That being said, it would be nice to buy a new Mustang, Challenger, Camaro, or whatever new muscle I may like and just drive it instead of work on it. Come to think of it Porsche 911???
