Like the idea but think the size is a bit too large for mounting on the glovebox door or in the interior for constant display. If the idea is to mount inside a glovebox or be hidden away, size is no problem. I too would eliminate the concept car and go with VIN's or build #'s so they can remain on the car if we sell them to another. Count me in on whatever you choose to do. I've already put the Chrysler wings some of you might have seen on Ebay that were being sold by a gentleman from Greece. They're only about 2" from left to right and made of Sterling Silver. Mounted them on the lower right corner of the glove box door and they add a really nice touch. If he starts selling them again think about adding them to your cars.
