I did get a good deal with my last car.
The thing is I'm an ex salesman, and don't have problems with haggling. At the end of the day all they can say is no.
My father asked for tips when he was replacing his car last year from a dealership. He walked away with a great money off deal, upgraded stereo, mud flaps and mats. They are always wanting to make a deal, I know, I used to, rather than loose one.
Try it, what have you got to loose, and you may get the deal that you want. Just remember to keep control of the conversation, don't let the saleman tell you what YOU want and can afford.
