Financing for new car buyers who owe more on their trade-in than the car is worth. The amount owed on the trade-in is added to the finance agreement of the new vehicle.
A type of financing offered to customers who are upside down in their trade-in, in which the amount still owed on the trade-in is rolled into the loan on the new vehicle.
When your trade-in isn't enough to pay off your old car loan, but you still insist on getting a new car and a new loan, lenders will be happy to create a new loan that includes the old loan's balance. It puts the borrower deeper in a debt hole.
