Couldn't be happier!
Kyle helped us and was fantastic! He worked was low pressure, willing to work with us and very professional! We highly recommend!!!
So far so good!
So far so good! This truck is the nicest truck I have ever driven. The stance, ride comfort and options are top notch. I went from a 2023 High Country that was having drive train issues but had all the creature comforts that you would expect in a top of the line truck. With the lack of confidence in that particular models 10 speed transmission issues, it became necessary to reestablish my confidence in my General Motors product.

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.

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.

I was here at the dealership a few months ago and I
I was here at the dealership a few months ago and I traded in my 2010 challenger on a 2014 challenger. The new one I purchased was an absolute gem. It only had about 600 miles on it. I thought “no way will this get approved” I’ll have to drive two hours back home without the new vehicle. Well I am pleased that I had Vincent and Kurt to help every step of the way. Between the two, they got me the best deal possible and I got exactly what I wanted. Never any pressure at all from anyone. The whole team there was exceptional to work with. I couldn’t have asked for a better car buying experience. Thank you to everyone. I definitely recommend going to Omeara. I will for sure be going back when I need to purchase another vehicle.
