Never owned a truck before..

by Texas Transplant from Tyler, Texas | November 12, 2019

I bought this new 2018 GMC Sierra SLT new in Sante Fe, NM. I never owned a truck before. I traded in my Tahoe 2011. I am truly impressed. It has all I could ever need for comfort, looks, amenities and performance. I bought a Red with gray leather interior and a sunroof with 5.3l V8. I did change out the Goodyear tires for Bridgestone Alenza Plus HD, which make a huge difference in ride. I get a lot of compliments on the look. I am very happy with my GMC. So Far

by DAVID from OSHKOSH | November 05, 2019

this is forth sierra Ive purchased. Has most of bells and whistles a lot I dont use. Rides nice and plenty of room. Heated and cooled seats are wonderful. Has 5.3 motor and plenty of power even when towing atv.No issues so far.

Comfortable for long hauls

by Denali for fun from Reno, Nv | September 18, 2019

Dives great, did a several long trips and never felt fatigued. Does lack some basic features I would have expected for a modem vehicle, push button start and proximity sensors to open the door.
