I dont mind the new cars as long as they don't have 30" wheels and that THUMPING music

I think these shows will be relevant for a decade or two. Hell I'm 59 and probably wont get to work on my own car till I'm 70+ (11 years from now). Things will probably taper off slowly as we get older or pass on. I was just talking to someone about how there may be a wave in the future as cars are passed down or people develop an interest "because their dad was into these cars".
