Is your research done?  Now what 

EV corner

The entire issue is blown out of proportion

You can’t put products before the science

Great negotiating requires great due diligence.

Avoid cash or shopping talk.

No matter what you offer, the dealer will try to bump you.

Don't acknowledge the asking price

Always ask for a better price at least twice before making an offer

Assertive, not aggressive                                                    

Hold your lips together tightly as the dealer plays his cards

Don't take the dealership’s position or attitude personally

ACV versus allowance.

Either way works but one at a time works best

Due diligence is your ammunition.
