WE have long winters here as well. What I plan to do is;
1. Change the oil, put stabilizer in the gas, 45 psi in the tires to prevent flat spots.

2. I intened to start the car at least twice a month, using a oil heater before starting. Let the car warm up and move it around the drive way to work the transmisson and steering. If and this is a BIG IF, there is no salt on the roads a short ride once in a while.
I don`t have the problem, but Decon is a good idea, mice love wiring.
Having said this, I`d like to hear from others who are more expirienced then I am
