Trade-In vs. Sell to Private Party: The $2,200 Question

The base case

Private-party value is typically 12–18% higher than dealer trade-in for the same vehicle. On a $15,000 KBB value, that's ~$1,800–$2,700 more in your pocket.

When trade-in wins anyway

Sales tax credit: In most U.S. states, you only pay sales tax on the NET of new car price minus trade-in. At 7% sales tax, a $20k trade-in saves $1,400 in sales tax. If the trade-in is within $1,400 of your private-party expected price, trade in.

States without trade-in tax credit

California, Hawaii, Kentucky, Maryland, Michigan, Montana, North Carolina, Virginia, and a few others tax the GROSS purchase price. In those states, private-party almost always wins.

The hidden cost of private sale

Time (typically 2–4 weeks to find a buyer), advertising, test drives, scam risk, title-transfer paperwork. If your time is worth $50/hr and the sale takes 8 hours total work, that's $400 of the $2,200 'gain' eaten up.
