Experience haggling with Processing fees?

[why?]

I'm sorry but it is a waste to negotiate before you test the car. Negotiations should last for hours, and you are wasting your time if you negotiate and then drive only to find you cant stand the car. Test the car first.

any advertising, shipping fee or other is bs, and if the salesperson really wants the sale they will drop them.

tax title and tags are a must though.

especially if you have 3 dealers do everything you can to drop the price as much as possible.
