Verify the out-the-door price

This listing is priced $3,391 below the typical Sierra 1500 AT4X, which usually sells around MSRP. An advertised price this far under the norm often means a mandatory dealer add-on package (paint/fabric protection, accessories, etc.) or fees aren't reflected here — they're added at the dealership and can erase the discount. Confirm the full out-the-door price before you count on this as a deal.

Negotiation Signal

  • On the lot 48 days — longer than 70% of Sierra 1500 listings in CO.
  • Price is down $3,391 from its original list of $84,785.

Time on the lot and prior price cuts are real negotiating leverage — a dealer carrying a slow-moving unit is more likely to deal.

What to aim for

~$76,481

  • Comparable Sierra 1500s (6) average $8,304 below MSRP — about $76,481 for this trim.
  • Listed $4,913 above that, so there's room to negotiate toward $76,481.
  • It's sat 48 days (longer than 70% locally) — that strengthens your hand.

A data-driven starting point from comparable listings and public incentives — not an appraisal. Dealer fees, trade-in, and which programs you qualify for will move the real out-the-door number.
