Shame on me for not thinking of that.
The road crews here do not use salt (too cold to be effective) so cars last a lot longer.
Our 'herd' goes back to as far as '41 (that one does need a little work).
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.
