I'm going to need to come up with one too at some point. Now that I know such a thing exists
In the past I've had sufficient run-ins with a few local police harassing me about not having a front plate mounted on my last daily driver (Jetta VR6 - made it nearly 7 years without anyone noticing, then one officer decided he was going to keep his eyes out for me and continue pulling me over until he forced my hand...), so I'd rather avoid it once the J is up and running.
