I always deal with the Fleet manager or General manager if there is no fleet man - both are on salary vs commission. If you order and immediately take delivery of your vehicle then there is zero floor plan costs involved - the truck doesn't sit there being financed by the dealership. The incentives vary by month and that will affect your out the door price. Find out if your dealer accepts the Costco $1000 off certificate in addition to the factory incentives. There are other incentives, such as Supplier pricing, 1st responder/medical and GM employee pricing. I ordered my Sierra 2500HD SLT in September and took delivery right before Thanksgiving - got a 2021. My dealer had a hell of a time getting my truck allocated as most have already been spoken for. Good Luck and Happy Hunting!!! Can't say enough good things about Key Buick-GMC and General Manager Derek Archer and salesman "DW" in Jacksonville, FL. Parts department manager, Scott Berni, is great, too - ordered my accessories and used my 21,000 points from GMC Rewards and got 25% off for factory sale to boot!!! They beat any dealership throughout NE Florida and customer service was superb!!! Tell him Sam Michael sent you!!!
