Frequently Asked Questions

Should I take a longer loan term for a lower payment?

While a 72 or 84-month loan lowers your monthly payment, you will pay significantly more in total interest. You also risk being 'upside down' on your loan, where you owe more than the car is worth.

Does my trade-in reduce my sales tax?

In most US states, yes! The dealership will usually subtract your trade-in value from the price of the new car before calculating sales tax, saving you money. This calculator factors that in.

What is a good down payment?

A standard recommendation is to put down 20% of the vehicle's purchase price to avoid negative equity and secure better interest rates.
