When I was at WDW the first time, I bought the MGM studios plate. The black plate with the silver. I still have it. It's never been on my car. When I bought it, I only had to have a back plate, so I wanted to put this on the front. But I wanted to attach a protective cover over the front so it wouldn't get damaged. Due to the thickness of the plate, I never found screws that would hold both the plate and the cover to my car...so it never made it on.
Last year, I got new plates and now we're required to have front and rear plates...so I still can't use the plate.
I'm not sure exactly what I paid for the plate. It might even still have the tag on it. I'll have to check. I did get it at MGM however, at the shop as we came off the backlot tours, not at DTD. DTD didn't have this one.
