A Beast when it comes to hauling!
I love how the truck pulls and rides when towing. It will give any driver the confidence to tow anywhere. I haven't had a single issue with it. I love the way it looks and couldn't be happier.

How easy it is to work with Johnson Auto Plaza.
Purchasing my new 2022 GMC Sierra was easy as buying something through the drive-thru. The salesperson, Chris Maneotis was awesome. He explained how my trade-in would go towards the purchase of the new truck and went over the financing and options. I would highly recommend anyone to work with Johnson Auto Plaza.
Best truck I have owned
I've owned every other American truck and this is my first GMC. I bought the 2500 HD Texas Edition. I absolutely love this truck. It's everything I could have hoped for and more. It is able to pull my 30' travel trailer with no problems. So now when we go out with our trailer I'll have no worries. The look and feel of the truck is outstanding. The 6.6L gas engine actually gets great gas mileage. It gets about the same as my Ford f150 ecoboost. Probably better on the highway. Looking at about 13 miles in the city and 15 plus on the highway. Definitely got a better truck for the price compared to any other american models with the same characteristic and options.

This truck is the truck that all others should look up to. It rides great, will tow a house, runs smooth, and gets great fuel economy. The Allison transmission is so smooth. The AT4 looks great too.

Fantastic service
The service was top-notch. I had a broken mirror and worked with Greg Mudd, who found me a great deal on a mirror, painted it, and installed it, saving me about $350. He was incredibly kind and responsive. It was a great repair experience when I had been anticipating a stressful one.
Great Truck (sans MPG)
Love everything about this Duramax Denali except the fuel mileage. 13-14 Mpg tops when not towing. Bought truck cause previous was stolen. Wish I still had my 6.2 High Country!

Mach-E from Phil long Ford Denver
I ordered from this dealer, even though it's 45 miles from me because the sale rep knew the Mach-E very well and had a car I could drive. Ford dealers closer to me were clueless if not down right stupid when it came to the full electric Mach-E. A few glitches on the delivery but over all a very good job by the sales person Brandon. Great ride!

If you are looking for a new car, I would strongly
If you are looking for a new car, I would strongly recommend Willie Boyd at Corwin Toyoya in Boulder, Co. He was attentive, knowledgeable, and went above and beyond to ensure I got the perfect vehicle for my needs. He patiently answered all of my questions, explained the features, and even took the time to demonstrate how everything worked. It was the best car sale experience I have encountered in many decades of purchasing a new car.
