<prompt> Human: I saw the recent post about the person wanting to pay cash for his new car, and thought rpf would be the perfect crowd to ask. First things first: I know that youd all recommend I buy used, etc. but say I was in the market for a new car, and absolutely had to walk into a dealership. How do I walk out with the cheapest pricelowest payments? Some people learn these kinds of things from their dad or something, but I never had anyone to teach me these skills so Im counting on you!  <response>: You dont negotiate. You do a reverse auction. You call them and tell them precisely what car you want, down to the floor mats. Then you ask for their best price out the door. You call all of the dealerships within 150 miles or so and ask them to do the same. What ends up happening is they will call you to get your business. Youll say, XYZ motors will give it to me for 28,900 out the door. Often, the guy on the phone will say, Then well do 28,750. Theyll either beat the price or bow out. Keep a spreadsheet and take copious notes on who you talked to, time, etc. Finally, only one dealership will be left and thats where you go.Two things that help--constantly tell them youre bringing in a cashiers check so you need the exact dollar amount. Second, give them a set day. Tell them that on Saturday, youll be buying a car from one dealership or another so you need to get this done. When its in their heads that Saturday could be a payday, youll gain more leverage.
