Worked with Cosmin on a used Porsche Cayenne.
Worked with Cosmin on a used Porsche Cayenne. Very friendly and professional salesman with a no-xx attitude. Didn't leave me waiting around excessively during price negotiation, and was willing to work with me to find a deal I was happy with. Finance was super quick and low-pressure, I didn't feel like I was being lambasted with upsells that I made clear I didn't want. Good stuff, Austin. Very respectful and professional staff, and I would definitely recommend doing business with these folks. Keep up the good work.

After any serving of a vehicle taking it through your car
After any serving of a vehicle taking it through your car wash before returning to customer. This might encourage more customer loyality. Oil change prices are too expensive. The expertise needed to do that job doesn't equalate to charging that amount.

I had a great experience buying my Audi here!
I had a great experience buying my Audi here! The entire process was smooth and stress-free from start to finish. The sales team was professional, friendly, and never pushy ? they listened to what I wanted and helped me find the perfect vehicle within my budget. The finance department made everything simple and clearly explained all the paperwork. The car was clean, well-prepped, and exactly as described when I arrived. I appreciated how transparent and efficient everyone was throughout the buying process. Highly recommend this dealership if you?re looking for an Audi!

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

Looked for a low mileage Acura TLX or TSX for six months
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. The sales rep called me very soon after my initial query. The entire buying process took an effortless one hour and I was on my way with the beauty,

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 have purchased a number of vehicles from this location under different ownership. The one good constant has been the service department and the service tech Dave Singh. Ask for Dave he will not let you down.

Sales and finance teams were extremely flexible and
Sales and finance teams were extremely flexible and attentive, listening to my concerns and working to find solutions. They supported 2 different test drives when I had a concern about a specific driving condition, being extremely flexible working around my schedule. Cam, Austin, and Alec worked together to provide answers to all of my questions regarding financing and extended warranties. When a last minute issue arose on a Friday afternoon, their maintenance department obtained the part and swapped it out on a Saturday morning to allow me to pickup the car that afternoon. Communication was excellent, receiving 2 status updates that morning.

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. Bill
