Car covers?

I still want to get one for my 73 and the 72 when it is done. I figured that a good one would be about 60 bucks...HAHAHA YEAH RIGHT. 60 bucks will get the one that just keeps the pine needles and bird crap off. After looking around at them on ebay, www.carcoversdirect.com and some other sites a real good, water proof, everything proof car cover is like $250. I still can't bring myself to spend that much on a blanket for my car. So for now I just wash my dart once a week.
