They likely won't give you anything for it. They'll show whatever they have to to make you happy and make some sort of a deal on a different car, but you can be sure they have no interest in your car. You are much better to sell it privately for around $3000 and use that money as a down payment on what you are buying. You will tend to get a better deal because the dealer doesn't have to go to the trouble of disposing of the trade in. Unless you're trading in a nearly new car, you're always better to show up with a handful of cash and no trade. Cobalts are good little cars. Clean it up as much as possible so it makes a good impression and then advertise it for sale. You shouldn't have any trouble selling it.
