I had an old Soviet-era made excavator digger standing on my property. It was standing out there long enough for trees to grow through the cabin and way above it. We cleared them and put a little grease here and there and it started like charm.

Another random example seems to be a Remington beard trimmer I had which recently gave up after nearly 20 years of service.

Edit: I guess we should make an honourable mention for the Opportunity Mars Rover.
