Black out your EZ-Pass!
 

Here's a good tip I came up with when I got my 8: you know how our regional EZ-Pass is an ugly white? Mask the small label area on it and then spray paint it flat black. Couple of coats will do it. What was once an eyesore - an ugly, bright white piece of plastic up on the windshield - is now virtually invisible. Try it!

The other thing to do - and I'm sure many of you already have - is to mount it so that it's completely hidden by the rear view mirror. I would think everyone would've figured that out, but I see many that are still visible from the driver's seat.
