Consider automobiles. Sure, when my dad bought his beloved 1960 Olds Super 88, Oldsmobile would love to sell him a new car in 1961. But his lovely old Olds still rolls across the road, despite his children's best efforts to destroy it.
I know someone who can trade one of his bikes straight across for two brand new Harley-Davidsons. So the old stuff often increases in value and is easily repaired where as the new stuff often becomes valueless as time marches on.
Case in point, my first laptop was costly. In the multi-thousand dollar range more than a decade ago. I can't give it away because it is useless. It will not function in today's world and it is impossible to upgrade. I am willing to bet, that there will always be replacement parts for the Corrolla. Why? It is the best selling vehicle EVER. So, there are enough parts in junk yards, to cover any "collecters" wishes for a VERY long time. That Olds you are so fond of, well, it is that way, because there aren't millions of them made. There are also far fewer of them in the junkyards to pull parts off of.
Today, you really cannot easily repair a body part on a new car, but you can "solder" the body of the Olds. Car guys will know what this means. Or perhaps not, the term Lead Sled is often something I need to explain to the youngsters.
And the car has great value, where as a 2011 Toyota will likely be long gone or difficult to repair in 51 years. If car lovers still exist in 51 years, my Olds will still have value and parts will likely be available. No so for the Toyota.
In days of old, manufacturers always wanted sales. But they also made things of lasting value, that could be repaired long into the future. I remember when Eastman Kodak would keep upgrading film and keeping the old stock available many decades after the cameras that used the film were long gone and hardly anyone used black and white versions.
Repairing the things we love can be costly so the items are tossed because a better, cooler whatever with twice the speed, double the memory, and half the cost arrives next year. Or on Tuesday, at 11:00 AM.
