Legally Register Any Car

You haven't had to deal with Illinois then I take it.
A political mess and the DMV is so bad (I'll try to be nice) I wouldn't recommend anyone deal with them that absolutely doesn't HAVE To. And ridiculously priced too. I could register all of my vehicles in Indiana (none less than 10 years old) for what any one costs me to renew here. And they're talking another increase.......I do see a lot of vehicles on the road that aren't worth the registration fee even if the owner got them for free, it's so high here.
What does it cost to register a vehicle there?
