An original 41 would never be roadworthy here if it was driven daily in our winters, unless of course you washed the undercarriage after every outing.....
Cars rust faster here than when I lived at the beach.
There are grain trucks still in service (and well maintained) from the '50s, although it is just more cost-effective to use newer ones (and the electrical systems are more reliable than the old 6 volt systems.)
The really neat thing about those vehicles, though, is that while they are a bit maintenance intensive compared to a modern vehicle, they are simple enough that you can work on them.
