Is it better to negotiate a discount off MSRP first and then compare that to GMS price? How can I see what GMS price is?
IS it possible to get a unit cheaper without using GMS? To clarify I can get GM family discount through my Uncle. Should I target a price to see if they will accept before telling them I have an authorization number? Then later saying I have GMS will that get me more of a discount or would I just not have to use the GMS authorization number?
