The Boomer argument may be true for some, but hardly a majority of us. I'm 69 - as much as I refuse to believe it - and am buying another '69 Mopar to add to my fleet.
I have friends 1 generation and 2 generations younger than me who are into '60s muscle as well.
I've been complimented several times on my '68 Road Runner by young kids.
We - and the musclecar hobby - ain't dead yet !

I understand the notion of brand-new muscle with all the comforts of home, but anyone with a pulse & credit can do that.
I'll take the visceral, wrenching-involved stuff, without all the electronics and nannies.
