Frequently Asked Questions
Does trade-in value reduce sales tax on a car?
In most US states and Canadian provinces, you only pay sales tax on the difference between the new vehicle purchase price and your trade-in allowance.
How much does paying extra each month save on a car loan?
Paying just $50 to $100 extra per month directly reduces the loan principal, which can shave 6 to 12 months off a 60-month loan and save hundreds in interest.
