Best place to sell trade without personal sale?

I don’t want to have to worry about being scammed, dealing with lowball offers, and wasting my time on showing the car. I just want to sell it for a fair Black Book trade-in price and use that to purchase a new car.

I’ve tried Carmax, Carvana, GiveMeThe VIN, and KBB. The only halfway decent offer is KBB from a local dealer followed by Carmax.

Any other suggestions?
