Due diligence research completed? Now what‪?‬ Deal Talk

Due Diligence research completed? Now what? 
EV sales are not up
The public is aware of Electric vehicle Fires and deaths
Manufacturers are hurting from EV failure
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
Talk what you know after they make 2 offers
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.
