On the wet coast of Canada... Vancouver area - there are many older cars. They do use de-icing salt / chemicals - but the number of days below 32F here, or near that temp - are relatively few. Lotsa rain, also, washes mud away.
Pretty good place for old cars, here.
Hehe - I got 27 years out of a (galvanized body) 1987 Plymouth Reliant, here. That's not bad - and the body itself was not corroded... but some of the unibody-reinforcing suspension supports, underneath, were not so good when I sent it to the scrap yard. Oh, BTW, there are many K car haters out there - but once '86 and later rolled 'round, the electronic feedback carb had been replaced by the (single injector) throttle body injection - by Bosch; the three speed A/T had lock-up on 3rd, and the engine had grown to 2.5 litres (the Chrysler engine, not the Mitsubishi engine) - and it had gained balance shafts. I really found that car to be a good one (and it had a split bench seat that could accommodate 6 people in a pinch).
