What changes a payment
Vehicle price, down payment, trade equity, APR and loan length all affect the payment. Lowering the payment does not necessarily lower the OTD price.
Longer terms
A longer term can reduce the monthly amount while increasing total interest and keeping the borrower underwater for longer.
Comparison order
