5 Overall rating
(21 reviews)Best truck I have driven! Highway speeds are great and feels like I’m driving a Cadillac.
Love the SLT and all the features it has definitely a great value and good driving truck with good suspension and quality
When the sales rep said “It has everything but the kitchen sink” I’m pretty sure it has those in it too! This is the most rugged yet luxurious truck I’ve ever ridden in much less owned. I can’t say enough about the features that makes everything from lining up with a trailer hitch to getting warnings via through the seat vibration when getting too close to something when backing up. Heck it even has a forward facing camera that helps up front. Two thumbs all the way around!
I love everything about this truck, so much I bought one. I got one with the 3liter duramax. Hopefully it’ll be the last truck I’ll ever own.
The features on the 2021 GMC Sierra was everything and more then what I expected. The value of the truck was decent considering the times we live in now. Would highly recommend GMC so far
