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!

Found a desk area with electrical outlet the chairs were kind of old and banged up, and it was kind of in the vending area. Wi-Fi was good for working, but the coffee area was all out of packets for coffee. Good service and they got me out quickly through the process for an oil change the first one on my vehicle and the first service at that location. It was good the The cut customer service was good
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.

From the very first visit, my Experience was exemplary. Justin was a fantastic person to work with easy-going. No pressure. Sales manager was also great. Same with the finance manager. Even the GM stopped in to say hi so far two weeks and the car is fantastic. I’m very happy I went with Volvo.
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.

I know how everybody always runs to write a review when it comes to anything going wrong! I think it’s equally as important to let people know when you have excellent service. I bought a 2014 Q 50 from Morgan yesterday and it was absolutely a seamless transaction.... The first time with visit in a dealer that has the hassle free attitude and fortitude, this was the first time that it was actually exercise correctly ! Morgan thank you for the care and time that you put in on my quest !!!! Kindest, AS You rock!66

Great experience, good people
I was in the market for truck and messaged Ryan after finding a great deal off the Sterling Auto website. This was one of the easiest, stress free, no pressure experiences I’ve ever had purchasing a vehicle. I was in and out the door in under 2 hours. Highly recommend. Everyone I met with was kind and straight to the point. I highly recommend and would happily do business with them again.

No-hassle purchase
I purchased a 2001 Toyota 4-runner from Levi's this week - I found everyone there very friendly and helpful. They had no objection to my taking the car to my mechanic to be checked out - even though we were gone over an hour! when we got back, I was out the door with my SUV in less than an hour! After I bought my Toyota from them, I read some bad reviews that they had received - looks to me like someone didn't have the car checked out before purchase and had problems - that's the buyer's responsibility as all purchases are clearly "as is." I would NEVER buy a used car without getting it checked out first! Overall, I am very pleased with my purchase and with Levi's.

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.
