Hey guys i was looking at a 2004 Mazda 3. It is manual with sport package. Moonroof and 6 cd changer. The guy was giving me a sticker of 18745. He was going to give me the spoilor too.... Is this a good a good amount or should I go lower? It seems high to me but... I am thinking of buying it for 320-325 a month at 4.9 percent interest. What do you guys think?
