This will be my first winter with my Boxster and I am NOT going to store it. I plan on driving it the entire season. I only have to drive 3.5 miles to the train station. Naperville is usually pretty good about clearing its roads.
As for salt when it starts to build up on the car I'll just wash it off in my driveway.
I have to store my sport bikes for the winter and I have so much fun on the Boxster to let it sit in my garage.
