Trading In A Car At Dealership ?

It will go to auction. Probably bought by a small cars sales company somewhere in your area. If it does not resell, then its back to the auction to be resold to a buyer from the nearest third world country.

KBB, NADA, Edmunds, Autotrader. Wholesale value minus 0% to 20%.

Look up the prices on edmunds.com and kbb.com. At least one of them includes "trade in" price. It's a guide. keep in mind that the dealer really doesn't need that old of a car with that many miles so he's not going to give you much for it compared to selling it yourself.

The dealer will send it to a "dealers only" auction.

I'd guess you can sell it for twice what the dealer will give you in trade. But, the price he tells you he'll pay will depend on at what point in the discussion you tell him you are going to trade in a car. If one of the first things you tell him is that you are trading it in he'll give you a high trade in price and make it up by not cutting the price of the new car as much.

I think you could sell it yourself with very little bother and still come out hundreds ahead, just price it on the low side, demand cash, not checks, and go with them to the DMV to do the transfer so all parties are protected. A clean, well maintained 2005 Accord will have buyers lined up with cash in hand if you don't hold out for top dollar.
