ok... I found this 2006 Jeep Wrangler... in great shape, extremely low mileage (12, 000 something miles)... It started at 19, 000 (technically 21K, but that was unheard of) and the dealer is offering 15, 900 for it. The Blue Book claims it should be 18, 000.... should I continue bartering it lower? It's a pretty good deal already. Please help.... I really want it and I intend on buying it regardless of the price, but what would you do? I want to strike the deal before the weekend.
