It wasn't meant to mean selling of the cars it was meant to provide an example of the simple fact that modern day cars depreciate every year whereas classics or old cars will or should hold thier relative value. Also one would hope that most could do the necessary work needed on a 60's or earlyish 70's car without too much trouble....even if they had to buy a manual or ask a friend to help that aspect of it should not be outside of most peoples reach.
