Think of it along these lines, soon as I get my Duster (economy car back then) running/driving good, I'm gonna tear into my next project, a 67 valiant 4 door! Now comparing that to modern cars would literally be like someone in 40 years bringing back a lowest option possible, base model dart with the smallest 4 cylinder they have. Just look at neons, economy cars. No they're not classics but there are ppl fixing em up. Not many maybe but still, I had a 98 4 door neon started out as a 2.0L and the previous owner swapped in a worked over 2.4 from a stratus, fun car! So the fact that people are fixing up slant 6 A-bodies, 4 doors etc. tells me it's not a far stretch to say people will restore v6 chargers, and maybe even 200s and darts in 30-50 years. Course by then they're won't be gas or roads so maybe not. Lol
