When I hear a salesman use words like that, I usually reach around to my back pocket and make sure I still have my wallet.
If you want the car, I would tell the dealer that you have your checkbook with you, and can pay $21,000 right now, or else you will have to go home and think about it.
When he counters, tell him you cannot go any higher than $22,000 and drifting out the door. Don't pay more than $22,500.
FWIW, those were my words and not the dealer's. I'm yet to get into any real negotiation with him on it, but here's what I do know. The dealer received the car in on trade for a new Cadillac CTS lease (they're a Cadillac-GMC dealer). The in-service date of the Genesis is May '10. Just curious, where did you come up with the $22,500 number, or was it just based off of what the dealer was asking? What's the typical mark-up of a car traded into the dealer? I'm sure the dealer has room to move, since he also put the previous owner into a leased Caddy.
Keep the suggestions coming. They've been very helpful thus far.
