Tinker Agreed, I always play the pressure the dealer game, use car gurus as an easy source of how longvthey have had the car. I like more than 45 days, most floor plan credit deals allow 45 day terms and a late payment grace window.. they need to move it before it costs them more. Always go on the last day of the month, preferably a weekday and go in about 4 hours before closing. If you are trading in, have your title with you, but don't tell them you have it. They have goals to hit, generally around the arbitrary end of the month. If they have been doing well, its out the window, they'd rather wait till next month. So ask them, if we can get to a deal, when can I take the car? Answer is, "Today!" They are in need of sales, if not, they will make an excuse of having it detailed for you and pick it up tomorrow. Walk out.
Assuming they are desperate, make your deal, then don't sign anything and say you have to run and get the title, or use an excuse of any sort to get out without signing. Then go have a coffee and call them back about 15mins later and " let them know, you had been talking w xyz car dealer, and they called with a phenomenal out the door price of 2k below them, so sorry, would really rather do business with you, but.." watch them drop their pants. You can't do it with everything, but when you have the power, TAKE IT.
