Good tip on that license plate bracket! It's now $7 shipped Prime. Mine has been installed cockeyed with sheet metal screws punched through the plastic since I bought the car (one of those I'll get around to it problems).
Here's a follow-up tip for your frozen rear windshield wiper. Mine was snapped off at the similarly rusted hinge. Since I'm a fan of the aero-type blades, I found this for under $20 on Amazon (out of stock now, but in typical Amazon fashion, there appear to be several identical items for sale):

I was a little weary on the fit and what I would get (I seem to recall it being $14). Ended up being the entire arm and wiper blade and ended up installing perfectly. I'll admit, it's a little flimsy (you can wiggle the arm up and down about half an inch); but it works just fine, is strong enough to hold poop bags (you may know what I'm talking about as a dog owner

), and most importantly, does a better job of cleaning the window then the front factory arms (both of which need to be changed on my X5 due to weak springs).
