Ive met plenty of guys my age, (70) who have new hi performance domestic cars, plenty of guys into all kinds of iron...... Many of these guys had older cars and some still do but they like their new Mopars, Mustangs, Corvettes
I met one guy (not that young) had three older mopars including a 69 GTX, a A body and something else I dont recall.
Guy shows up at a cruise in a brand new Porsche....What a car and why not, good for him
I turned 18 in 1970, graduated HS June 70 so I was I was at the later stages of muscle car era, when 1973 came, the gas crisis, safety bumpers, as far as im concerned that age was over
In late summer 1973 when I got home from active duty I went to Briggs Chevrolet, was looking at a new Monte. They had two 73 super sport Chevelles with 454 engines, I could have gotten some deal on those cars, brand new and they couldn't give them away
The hobby isn't going anywhere so relax and enjoy yourself
