My Miata didn't have a front plate. It "fell off". And when it fell off it apparently hit the ground pretty hard (repeatedly), scratched up, dented, with the mounting brackets bent. The works. Fortunately I "found it" and stuck it in the trunk to remount it someday. It was there in case an officer commented on it. . . I did have the front plate with me, after all. . . it just . . . fell off recently.
On the BMW I didn't mind the way the front plate mounted. It seemed fine to me so I've kept it on.
The Jeep. . . don't really care. Though I think the plate gets mangled from time to time since I scrap the front bumper on rocks.
