.  I'd like a little more science behind your guys' claims. My understanding is that rust = oxidation. Key root of that word "oxi" coming from oxygen. Science tells us that cold weather is "denser" i.e. contains more oxygen per unit of measurement, so by those standards a car should rust faster in a cold environment because it is being expose to more oxygen.  I believe you will find more of a correlation between rust and humidity than rust and temperature. My garage is dry and sealed extremely well from the elements. It's warm in the summer, cold in the winter and I see no difference in how fast things oxidize. This house has been in my family for nearly 00 years as well.  I think the storage environment is irrelevant if you drive in snow/ice/salt. You car/motorcycle/didlo WILL rust being exposed to salt.
