Frequently asked
Is sales tax charged on the trade-in?
In most states tax applies to the price minus the trade-in value; California, Virginia, Michigan (partially) and a few others tax the full price — set the trade-in to zero in the tax field if so.
What term should I choose?
Shorter terms cost less in interest and keep you from being underwater; 72–84-month loans lower the payment but can double the interest paid.
