IS not the HUGE sale this blackFriday a bit better then this supplier program?
I mean I saw 15-20% off MSRP which is HUGE.
CORRECT! Dealerships are free to give you the same deal as a supplier discount, sometimes the kickback from a "supplier discount" from GM is so small they don't even bother with doing the paperwork.
Tell them you can get supplier discount from me but I forgot my password. (truth)
Haggle the price, you can get the same or better deal without a supplier discount.
