その価格で購入する意思がある人だけコンタクトしてきてねって事だと。

値引き交渉可ということです。直接売り手に連絡し、値段の交渉をします。

Setting an Asking price through a classified listing is a great way to get the price you want for your car. Unlike an auction, potential buyers will contact you directly to negotiate a price they’re willing to pay and you’re happy to accept. It may take longer to sell than by auction because there’s no specific end date, but you’re still likely to get the price you want.

ディーラーで購入する場合も、Asking priceの定義で交渉するものなのでしょうか？
