In Illinois thre is an exemption for "Show & Race Car Affidavit"
You have to go to the emmissins place and ask them for one .
They don't like to publicize it, and not to many people know about it.
It took me a while to find all this out.
There is a catch however, you must have limited driving insurance and send them a copy of the declaration page.
In other words you are telling them that the car is a specialty car and you only drve it to and from shows, and events.
Well heck, in the summer I'd say that's everyday!!!!
