How to use these rules
-
Check the ceiling before you compare offers
If a quoted APR looks extreme, compare it against the Illinois cap above — and note that a specific statutory exemption can apply to a particular product.
-
Verify the lender is licensed
Use the regulator named in the table to confirm the lender or sales-finance company may legally serve borrowers in the state.
-
Know what is secured against your car
A vehicle title loan is secured by the car itself. If the state permits it, understand the repossession terms before you sign anything.
-
Budget for tax and fees separately
Sales tax and title fees are financed along with the car, so they raise the amount you borrow — and therefore the interest you pay on them.
