Here in IL, you pay sales taxes on cars purchased from a dealer. If you purchase from an individual who is not a dealer, you pay $25. No annual taxes either, although there may be cities who do charge them. Also no mechanical inspections. You do have to get an emissions inspection on a gasser every two years, but the state pays the tab.

Our plates are pretty expensive at about $80 a year, but considering what we don't have to pay, I don't mind.
