Where in IL are you moving to? Im from the northwest subs of Chicago in cook co. (Worst place to be for police) and I've been running around with no front plate for 8 months with my mark and have never gotten hassled..I think they tend to look past the mark viii being its generally an older persons car lol..now a t/a, camaro, mustang on the other hand..may not be so lucky. Didn't have one on my impala for a while either before I totaled it and didn't have any problems there either..
Basically I say f*ck IL and their dumbass front plate law, not worth drilling holes in an unmolested front bumper..besides it looks terrible with that huge bracket.
