I had exactly the same issue, garage full of bicycles and kids stuff. Got my Z a couple of months ago & planned to keep it in the street but soon started to work on hanging the bicycles up and getting rid of loads of crap. Z now snuggly tucked away in the garage mon-fri most weeks. I wasn't so bothered about it weathering outside (I agree with tjlazer on that score), I was more concerned with it sitting around and just getting colateral damage from bad parking or plain vandalism. but now I've started to use the garage, I'm hooked.
