[originaltext] After you decide what kind of car you want, which options you

After you decide what kind of car you want, which options you need, and how much you can afford to spend, you should shop at several dealerships. Buying a car is one of the few purchases that you will make in the United States that allows for negotiation. In the case of cars, new and used, the sticker price posted on the window is not fixed, and the car dealer will expect you to bargain. It has been estimated that fewer than 20 percent of all new car buyers end up paying an amount even close to the list price.
   To save the most money, use the following strategies when you negotiate. In the first place, don’t mention that you have a car to trade in until you have agreed on a price for the car you want to buy. If the salespersons know in advance, they may quote you a high price for the trade-in, but the price of the new car may be adjusted to include the added amount. In addition, buy a car that is already on the dealers lot instead of ordering a car. The dealer has to pay insurance and finance charges for every car in the inventory and is usually willing to sell one for less money in order to reduce the overhead expenses. Furthermore, try to buy your new car at the end of the year, just before the next year’s models arrive in the fall. Dealers are usually glad to move these cars off their lots to make room for the new models. If you can’t wait to buy your car until fall, at least wait until the end of the month, when the dealer is trying to reach a set sales quota in order to earn a bonus from the manufacturer. Finally, don’t mention to the car dealer that you intend to pay cash or use a bank for financing until the deal is closed. Some dealers will offer a lower price if they believe that they will have the opportunity to arrange the financing and collect a commission.
