Frequently Asked Questions
Should I trade in my car at a dealership or sell it privately?
Selling privately almost always nets 10% to 15% more cash. However, trading in at a dealership is faster, avoids dealing with strangers, and in many US states provides a valuable sales tax credit that narrows the gap.
