My father had minor interest in some post-war older cars, but in general he was not a big fan of collecting anything pre-war. he was born in 1924 and his first car was a model t for $10 and then got a worn 37 Ford sedan in high school and then a 40 Plymouth sedan. he lightly customized the 40 Plymouth and kept it until the early '50s. in the meantime, my dad had bought a used 50 Ford convertible and then a used 52 ranch wagon. he customized those also slightly. in 1955, he traded the ranch wagon in on a brand new Volvo sedan. then another Volvo in 56. and then a new Fiat 600 multipla in 57. and then a used 59 thames window van. after that in 1963 a used 62 Convair greenbrier. are you noticing a pattern... seems he was always buying something. newer even if it was used.
he did step back twice then. My mother finally got her driver's license and he bought her a nice clean 51 Chevy sedan with a power glide. that was her car for a while. the second time he stepped back and bought something older was buying a 1957 Chevy wagon and then a week later trading it in on a 1956 Pontiac safari. then he sold off mom's 51 Chevy sedan and she started driving the 56 Pontiac. and it had air conditioning! after selling the 56 Pontiac there was a 57 Pontiac 4dht. sold that too and bought a nice 64 Malibu 2dht. My sister totaled that out and then dad bought a used 68 oldsmobile 442.
then he came across a screaming deal on a pair of 51 Chevrolet sedans for sale. he bought them both and tinkered with them some. My brother bought one of them and my dad sold the other when he bought a 64 falcon 2dht. and then he bought another 64 falcon and then another 65 falcon convertible and then and parts cars for them. and a couple of 65 rancheros too. and somewhere in the midst of this also bought a 60 El Camino. he was playing around with these older cars because finally the company he worked for started giving him new company cars starting in 1964. a Chevelle sedan. and then a 67 Bel Air sedan which lasted only a few months before the company recalled it and gave him a new 68 Bel Air sedan as a company car. so that brings us up to about 1974 I think.
I can keep going on and on but I'm sure I've already bored you stiff. I'll try to remember to post about the cars from 1974 on.
main point I want to say is that he basically kept buying newer and newer until he started getting some interest in stepping back a decade but never back before 1951 vehicles.
when I bought my 1923 Buick touring he said nice old car and i took him for a ride... then he mentioned he had no desire to have a car that old. he prefers to drive something that can keep up with the traffic. so I guess my dad did influence me somewhat... I like old stuff. and for a while I even liked tinkering with it. but now with my 74th birthday soon I really don't want to work on cars anymore. I'll tinker with my 41 Cadillac to keep it running... but I'm not buying anymore cars other than for transportation. but I do appreciate seeing old cars in the hands of others that do love them...
