My neighbor pulled up with this on the trailer today...

Oh, yes! The cars around here rust LIKE CRAZY!

They dump tons and tons of salt on the roads around here at even the slightest bit of snow. Enough that all our cars are covered with white powder from driving in it. Plus, it is very humid here at certain times of the year, which adds to the problems...

My 2004 Jeep Grand Cherokee has a large spot of rust under one of the doors because i use it whenever there's ice/snow... It appeared over the course of one winter from good paint...
Plus, there seems to be some kind of unwritten rule that Okies let there cars rot into a heap (and then try to sell it for 20 Grand)
