This past winter was bad. we got over 750cm (295inches)
Freezing rain, and a ton of salt residue on the road.
I am planning on getting:
Snow Tiers ( A MUST)
Seat covers (For the leather)
Under Coating ( Wax- Oil not sure yet)
Plastic for the carpet
Floor mats (With high outer walls to prevent leakage)
I'll do anything to keep it prestene condition.
That is incredible the amout of snow you get. With that amount of snow you will really have to keep up on it. I bet they really put down the salt on your roads. Good luck.
