Absolutely stunning vehicle. Pure luxury pick-up truck. Serious power, w/a 6.2L V8 engine; smooth, wonderful ride, lots of driver convenience & safety features; comfortable seating, roomy cab interior....I could go on. GMC has left nothing out of their Sierra Denali line. Beautiful truck - everyone Ive talked to feels the same. Commanding presence on the road. Tops Dodge Ram & Ford models, in my opinion. I have a 2020 model. The 2023 model tops even THAT!!!
