Mike's Notes
I personally inspected this Sierra AT4 and I have to tell you — finding a 2020 with only 8,099 miles is like finding a unicorn. The Pacific Blue Metallic paint is absolutely stunning in the sun and the truck presents like it just rolled off the showroom floor. The CARFAX shows two owners with a clean, no-accident history, dealer-serviced its entire life at Jerry Seiner GMC, and the previous owner even had a fresh battery installed earlier this year. What really sold me is the option list — this thing has the upgraded 6.2L V8 (not the base 5.3), the Technology Package with the 15-inch head-up display, the power sunroof, ventilated seats, and the full suite of Driver Alert safety tech. If you've been shopping AT4s in Denver, you know these are hard to come by in this condition — this is the one I'd tell my own family to buy.

Features and Benefits

• Full Driver Alert Package II Suite – Adaptive cruise, automatic emergency braking, lane keep assist, and blind spot monitoring reduce fatigue on long Colorado drives
• HD Surround Vision & Rear Camera Mirror – See everything around the truck when parking downtown or navigating tight trailheads
