I want AT4 as well but, most dealers are not moving on the AT4 regardless of the engine. They are welling to move on Denali or fully loaded SLT. I got a quote today on SLT with a baby Duramax MSRP $62785 minus $6500 GM discount plus first responder and costco discounts. Final price $516500 plus tax, tags and $499 dealer fee. If I go with % interest $6500 goes away. This deal is valet till the end of the day, Wednesday 6-3-2020. Spoke to my financial adviser and she said just pay cash for it if you can't get better deal elsewhere on Monday or Tuesday. My problem is I DO NOT LIKE CHROME. I might just wait until September to see if I can get the truck I really want instead of settling for one. I don't need truck but midlife crises wants one.
