I am amazed at how rust free any Porsche I've looked at is. Even the bolts never are rusted together. Hence I have zero worries about driving the car year round, as it was intended. These are not rare, special cars. Drive em hard and long, put them away wet, it'll still start up and look just as good the next day.
I had a good amount of fun drifting my Boxster around in the freak snow storm St. Louis got over the weekend. Then got home, and took out my rally car for a spin.
