Unless someone has revoked the laws of physics, I know of no way to "affix" to the bumper without some form of hole in the bumper.
Candidly, if you buy the Porshce mount kit, and buy a quality plate trim, it doesn't look THAT bad and you do get used to it.
Now, if you park in Carlsbad and the meter maid catches you without a plate, you get a $50 ticket.
Even I got pissed at this but then again, I KNEW I was supposed to have one, so I sucked it up and paid.
BTW-We do NOT think you are a MORON.
But you were whinning a bit!
Stay with us, we are a good group of guys!
And girls too!
