Start with the same vehicle
KBB separates trade-in and private-party values because they describe different transactions. A dealer also has preparation and operating costs to cover.[1]
- Match the year, trim, mileage, condition, title history and location.
- Get at least two written offers using the same vehicle information.
- Compare realistic private-sale prices. An unsold asking price is not proof of value.
- Use a range if your vehicle is rare, heavily modified or difficult to compare.
Seller worksheet: what will you keep?
For each route, write down the expected price, selling costs, loan payoff and likely payment date. Ask your state tax agency whether a trade-in tax benefit applies to your situation; do not assume one.
Example only—not typical prices or a guaranteed outcome
| Item | Private sale | Dealer offer |
|---|---|---|
| Agreed or expected price | $27,000 | $24,800 |
| Estimated selling costs | −$450 | $0 |
| Confirmed loan payoff | −$18,000 | −$18,000 |
| Estimated proceeds | $8,550 | $6,800 |
Do not use dealer profit as your pricing formula
A retailer’s average profit does not tell you what it paid for your exact vehicle. Use actual offers and comparable sales to judge your options.
Buyer worksheet: what will it cost to own?
- Write down the vehicle price, taxes, registration, inspection, transport and immediate repairs.
- If buying from a dealer, request the itemized out-the-door price in writing. Remove unwanted optional products before signing.[2]
- If financing, compare APR, loan term, finance charge and total payments—not only the monthly payment.[2]
- Read any warranty or return terms. Do not assign value to a verbal promise.
- Use the inspection report to price needed tires, brakes, maintenance or repairs.
Choose the trade-off that works for you
A private sale can leave more room to negotiate directly. A dealer offer may be easier to complete quickly. Compare the likely proceeds, workload and timing before choosing.
Frequently asked questions
How much more can I get in a private sale?
There is no reliable fixed amount. Use current offers and comparable vehicles, then subtract your selling costs and loan payoff.
Is the cheapest advertised vehicle the best buy?
Not necessarily. Inspection findings, fees, financing and immediate repairs can change the total cost.
