Bargaining is a creative process. But first you need to find a dealer who has the car you want. There is no need to arrange a tour of car dealerships, you can go to https://all-cardealers.com/choose-your-state/ and choose your state. Then from the variety of dealers choose the nearest to you and read the reviews and experiences of other customers of the dealer.
In addition to car availability, it is also easy to assess the dealer's willingness to bargain: most offers are already posted with a discount. But it is more of a ''first'' rather than a final price. It can be laden with additional terms, but it will be given without any efforts from your side - even by phone.
The real bargaining will begin with a personal visit to the showroom. Of course, sales managers are not eager to reduce the price at once, losing profit. They start with small concessions, for example, in the form of free accessories. Something from the ''gentlemen's set'' - mats, mudguards, a grid in the trunk, engine protection - you can easily be offered as a gift. If that does not impress the buyer, you can use a stronger argument - winter tires, alarm system, body protection film. And when the subject of bargaining is a car that is yet to be ordered, the step towards the buyer can be nullification of the price of this or that option. Another popular dealer's argument is discounts for maintenance of the future car.
