Don't assume you can get $2,000 on a new car. For example the price difference between a 2008 Nissan Rogue from Invoice and MSRP is only $900.
Don't count on a Sales Manager going under invoice because then you're going into holdback.
I had a guy who wanted a 2009 2.5S Altima that's MSRP was $22,745 for $19,000 so we told him to walk after a while of arguing
