A car coming from a "rust free state" does not mean its rust free, and a car from a "rust' state does not mean its rusted. These are 50plus year old car made of steel, rust is rust. In 50 years any car will be subjected to a variety of conditions, evaluate it for what it is.
I understand what you are saying, but there are states that naturally cause vehicles to rust faster than others, some in as little as 2 years, like ohio,new york,ect and I was just asking what states are better to look for a car.
