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!

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.

Looked for a low mileage Acura TLX or TSX for six months and I found this car near me. It was nicely detailed and looked well cared for from the posting on Cars dot com.

Rafeal was my contact there and he was great.
Rafeal was my contact there and he was great. He went above and beyond to communicate share photos and video and was very transparent. As a matter of fact the whole process and everyone was easy to work with. Not the dealer where sale and sale manager go back and forth to do some crazy negotiating. Open transparent and fair dealing. Rafeal was an advocate throughout and in and out with anew car well less than an hr after trade in paperwork
