Compare the full cost—not just the payment
A lower payment can come from a longer loan term rather than a smaller debt. Ask for a written breakdown showing the vehicle price, trade value, payoff, negative equity, down payment, taxes and fees, and any optional products.
Then compare the amount financed, APR, term, finance charge, and total payments. Choosing a less expensive replacement vehicle may reduce the overall borrowing need, but it does not cancel the old balance.
Make the rollover visible
For illustration, a $25,000 replacement vehicle plus $3,000 in financed negative equity starts at $28,000 before taxes, fees, optional products, or a down payment. Ask the finance team to show each item separately.
