For the most part I leave mine in the garage over the winter. But I will take it out on a nice clear day to circulate the fluids. Had a storage problem the just came to bite me in the butt 2 weeks ago. Seems all the seals had dried up and it sprayed oil and coolent all over the engine. 3 days in the shop replacing stuff. I also learned a lesson on March 10th 2007 about driving in the winter. First nice day in a while. Stuff thawing, out driving. Stayed out late. Hit an ice patch that had re-froze and went shooting off the road at 20mph and hit a ice berm. Up and over. $5000 later got the car back.
