My experience with Mark Mazda was fantastic. Smooth and easy. I was called by Bryce Young immediately after I left the cars.com site and ultimately purchased the car the next day.

2021 GMC Sierra 3500 Denali review

Truck is a Solid vehicle overall.

April 5, 2021
By Review from Tennessee
Owns this car

Has a really Big feel to it. I currently use mine to pull gooseneck trailer. I haven't had a load yet that I couldn't pull. The downsides to this truck is to me I feel it could get better fuel mileage. Also I had trouble with #4 injector...dealership replaced it. Now my AC doesn't work all the time. Although it sounds like it's blowing it isn't.
