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.

2021 GMC Sierra Replaced Engine
Dave Singh was the tech representative handling the whole communication and repair on my vehicle. He was very professional and responded quickly every single time, I had to brong my vehicle from another shop which was awful and luckily Dave and Mike Marrone changed the overall experience. Keep up the good work!

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.
