LZ: I don't know where you live, maybe you can think of move to an apartment with indoor parking (next year). I once rented an apartment which is close to Ikea for four years, and it has indoor parking. Inside the garage, there is a water tap and hose inside that you can wash your car. I washed my car, dried car body, moved back to my own parking spot and let it dry overnight. (Even outside is minus 30). And the garage is always above zero, and it is free since you rented a parking spot.
