I live in New Jersey too, where front plates are required. It's a $48 fine... My last car was a riced up 97 Eclipse and I never had a front plate on it either. Got a few tickets in the Eclipse... but none so far in the Crossfire. I think cops can understand you don't want to ruin the look of the Crossfire... Take a look next time you see the rare Lambo or Ferrari.. most don't have front plates either.
I got pulled over once and I thought it was for the plate.. but he gave me a warning for my tint! LOL - He never even mentioned the fact I didn't have a front plate.. guess he didn't notice.. but he noticed I had tint. Wierd if you ask me.
BTW New Jersey laws suck!
