I believe the history on this one, was that the original owner had health issues shortly after purchasing it new. I think he might have only road it about 100 miles. Eventually he passed away, and it sat where he last parked it ... under the carport. Although I agree with covers trapping moisture, especially in humid climates like Florida has, but I'm told that this one didn't have one, and it might have benefitted from it. The current owner says the rust was caused from sideways rain.
