Why state matters for your payment
Two buyers with the same vehicle price and APR can see different amounts financed solely because of sales tax and fees. Rolling tax and fees into the loan increases the principal and total interest; paying them at signing raises cash due but can lower the financed balance.
Use the Illinois calculator to stress-test down payment, term length, and APR before you negotiate.
