Move to Sunny QLD AU!! No snow, 20-30c year round, heaps of Holdens, no mustangs and we have RUM! What does extreme cold do to paintwork?
Cold... nothing that I know of, it does seem to do more damage to interior stuff... it's the salt and snow that gets stuck in all sorts of places and makes RUST.... most cars in MN have rust in 10 years that is through panels...
