There's another grand right now for anyone owning a 1998 or up explorer, explorer sport, or sport trac.
And all the financial advise above is good, but can be wrong, depending on the vehicle and dealer. Some dealers have holdbacks from other dealers because of transfers, etc. Some charge rediculous doc fees. Some will give you a great price, but screw you on trade, accessories, etc.
Best bet is to walk in, tell them what vehicle you want and with what features, and tell them you're willing to give them a "$300 gross." Also, tell them you have no trade. Sell the trade outright in the paper, or online. The "gross" refers to the amount of money they make on the vehicle regardless of any circumstances. That's basically saying you get all incentives, and you'll pay them $300 more than what they ultimately have in the vehicle. If they don't agree, tell them see ya. Another dealer will.
One thing to keep in mind is that although you're trying to get the best price possible, the salesman whose time you're occupying, the manager, the F&I guy, the detailers, etc., as well as the dealership itself has bills to pay. A good price is great, but a reasonable profit is acceptable for them. That's how your salesman feeds his family.
