I may just have to seal old Gump up for winters and vacuum wrap her to keep her dry.
What about the periodically-on-sale $170 Harbor Freight portable garage? I have one but have not set it up, so I can't speak to just how bad it might be, but it's a thought. I know, it's galling to contemplate spending more on the tent than you did on the car that goes in it! -- Jim
