We had my son's graduation party last weekend. When I pulled the cover off my Dart I had 15 teenagers on and in it immediately. So there is still alot of interest with the young guys and old cars.
Those kids were there already. there's passing interest and real interest. When the kid offers you money for it it's more than passing. Muscle cars are soemthing different, not something desireable for them. I see this declining until the musclecasrsz become like the pre-WWII classsics. Collectors will have them, some will occasionally drive them, but as far as overall interest it's waning. Mine is the last generation to be able to buy them used and drive them to highschool and many enthusiasts in my age group are buying modern muscle because they like them better. It's only a matter or time.
