How do I know if a buyer's offer is fair?
Compare the offer to Kelley Blue Book's private party and dealer trade-in values for your specific vehicle, mileage, and condition. Also run your VIN through Carvana and Edmunds for additional data points. If multiple sources land in the same range and the offer you received is within 5 to 10 percent, it is likely fair. If it is significantly below all estimates, it is worth getting another quote before accepting.
