2020 GMC Sierra 2500 SLE review

2020 GMC 2500 AT4

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.

Terryville Chevrolet review

Everyone was very friendly and helpful.

Everyone was very friendly and helpful. From Linda at the front desk to the Finance manager who took extra care to make sure I understood everything about my auto loan. My sales guy Chris B, didnt apply one drop of pressure. He just did what I asked and that was to sell me the car I wanted. I let Chris know I will be returning to him for my next purchase.

Bought a 2021 MB AMG C43.

Bought a 2021 MB AMG C43. Dave and Tess were most helpful and flexible in closing a mutually beneficial deal. Highly recommend.

2020 GMC Sierra 2500 Denali review

Most convenient options on any vehicle I've owned.

Great power and yet great economy. Love the safety features with the cameras and side vehicle warning. Camera that shows side of vehicle, including trailer when turn signal is on is great. Also appreciate the bed camera for hooking up gooseneck trailer.

Loehmann-Blasius Chevrolet review

I got a good deal on the car.

I got a good deal on the car. Tyler was great to work with. If there was one thing to complain about, it was the time it took to work things out. I was there for four hours, just wish we could’ve cut down on the time.

This is your Truck

When looking at price point vise equipment, This is your truck. I looked at every 2500/3500 on the market, same vehicle equipment and price. I chose the Duramax.. HP, Torque of this Diesel, truck equipment that the SLT price point had everything that I wanted for safety, appearance and comfort, none other came close. This is your truck...

2020 GMC Sierra 2500 Denali review

So far have loved my 2020 2500 HD 4x4 diesel

I have owned my truck for a month and two weeks. Two weeks after owning it my power steering went out for about 25 miles then was OK again. Last week the check engine light went on and after about 25 miles it turned off and it was OK a week ago I entered my truck to start off for the day and everything was dead absolutely had no sign of life. The dealership has now had it for exactly a week and they cannot figure out what’s going on. They say they’re having problems receiving communicating. I sure hope I will continue to love my truck. It drives like a dream and pulls like an ox.
