2020 GMC Sierra 1500 SLT review
Great truck!
I bought my 2020 with 36k miles a couple of years ago and I now have 60k miles of trouble free very enjoyable driving. It was expensive, but worth every penny. The ride is so quiet and comfortable my wife and I prefer traveling in it instead of our 2018 Acura MDX which we also love. The 5.3 V8 has plenty of power and towing ability. The multi-function tail gate is genius, I hope to never be without one again. We so enjoy all the bells and whistles, especially the wireless phone charger. So glad I bought this truck!

2020 GMC Sierra 1500 SLT review
Short turn radius
I purchased pre-owned 2020 1500 SLT in February of this year. The truck rides comfortable and has plenty of room front and rear. My and I both enjoy it. My only drawback is the turn radius (lock to lock). It lacks compared to my wife's 2018 Yukon SLT, or the 2016 Ram I traded in. Have to many times maneuver twice to park it going forward or reverse. Otherwise happy with our purchase.

Great Truck
I did my research and test drove several models. The GMC 1500 Duramax does everything I want it to do and more. Great gas milage, nice power and very comfortable.

Mark Wahlberg Chevrolet review
Big thank you to the service department at Mark Wahlberg
Big thank you to the service department at Mark Wahlberg Chevrolet! I was in Columbus traveling 500 miles from home when the tire pressure light on my 2018 Silverado came on with a zero pressure indicator. The guys in service were empathetic to my situation and immediately started inspecting the tires and checking the sensors. Turns out the tires were fine. One of the sensors had gone bad. I had peace of mind to drive home eastern PA. I asked what I owed and was told no charge, glad they could help. Thanks again.
