Very nice Lebowski! That would be very unnoticeable for anyone to see. The model that cskmom posted are fine too and some I have seen on ebay would actually look like a crown moulding on top of the plate cover if the cover was black. The one I saw at Costco looked like a photo camera stuck on the back and protruded pretty far out....it looked like crap but in fairness it was on a Toyota Corolla so I guess it blends in with the rest of the car.
