I really do not expect that a newer fridge will last as long. I may try and find something in brushed aluminum off Craigslist which has been sitting in someone's garage since 2000 when this one eventually goes.
I have an aunt who has had a fridge running without issues since about 1962. It is all white ceramic over stainless steel and a thing of beauty.
This is the kind of product engineering modern companies seek to avoid.
I seem to recall a Heinlein novel about inter-dimensional travelers who wanted to take over the world by destroying the economy. The first thing they did was found companies which made products which never wore out (razors and cars).
