You'll need to make any remaining payments that are due up to this point. If the amount you’ve already paid for the car (including the deposit) is less than half the total amount payable, then you’ll need to make an additional payment to pay off the difference.

If you haven't paid half of the outstanding amount and you’re experiencing financial hardship at any point during your agreement, some lenders may offer financial assistance.
