Not enough younger people in this hobby...

Out here on the west coast, you can still find quite a few 60's Mopars, just not any super-desirable ones like 2-door hardtop '68 Darts. I don't know what your cutoff limit is on affordability either (I've noticed the '63~'66 A-bodies are pretty affordable). Might wanna make sure your nephews even WANT an old 60's/70's American car. My sons were a little lukewarm to the idea of owning a car that was the hot ticket in MY generation. There's PLENTY of 80's/90's cheap mustang GT's......I mean, that would at least keep them out of an import.
