I'm lucky that we have all year driving weather here in the south. I truly feel for you guys that need to worry about what will happen to your cars over the winter, mice, stall gas, and the like. You spend your time taking care of the car only to have to spend time in the "short" driving season fixing what you have no control over. (no political statement here
)
Since there are so many things that do work, is there anything that has been tried and did not work and should be avoided?
