Frequently asked questions

Compare the total cost, not the monthly payment. A longer term lowers the payment but usually raises the total interest, so add interest and fees for both offers.
Only if the term and fees match. A 4% loan over 72 months can cost more than a 5% loan over 48 months because interest accrues for two extra years.
Get a pre-approved rate from your bank first, then let the dealer try to beat it. Manufacturer subsidised rates (0-2%) are often worth taking even if the price is fixed.
