I live just above Los Angeles and have five vehicles; all have no front plate and four are illegally tinted. I have never been stopped or cited for no front plate and my wife has got one cite for tint. Not bad. A lot of it is where you live.
A big tip in California is the citation has to have the "Correctable Violation (40610 VC)" box checked "yes". If not, there is a good chance that you will not be offered the fix it for a lower price option.
