I can pretty much drive it at least 2x a month during the winter. Drove once to deliver Xmas presents, driven in about 42 deg., and as said before, it doesn't really rain constantly. I think 2010 was our wettest year since I've had mine on the road in 2006.
This year: change
oil, and work on some rear boxes to add into the trunk for additional storage. That should be all. Maybe I'll try to clean the undercarriage this year!
