Nathan and Kevin was great.
Nathan and Kevin was great. They made the car buying experience very simple and made sure that all of my questions were answered. Im very happy with my new Envista.
A little expensive, but comfortable, quiet, smooth ride.
A little expensive, but comfortable, quiet, smooth ride. Great performance out of the 6.2L and better than expected fuel economy in the low 20s. Outstanding interior and good looking exterior, especially in the Downpour Metallic color. I don’t have 700 miles on it yet and have owned it for 3 weeks. Therefore, I can’t pass judgement yet on the reliability, but so far I am very satisfied. This replaced an 8 year old Ford F150 that served me quite well with only a couple of issues in the 100,000 plus miles.

The entire team at this location far exceeded our
The entire team at this location far exceeded our expectations! Our sales consultant Sandi was extremely easy to work with, and he had our best interest in mind when working on a deal for a new truck. When it came time to financing, Alex ensured we got in and out with exactly what we needed. He provided us personal stories bridging to his recommendations that help guide my wife and I in a direction that surpassed what we originally had in mind. Finally, throughout the visit Edgar and Manny ensured we felt comfortable as we worked though a deal that would ultimately have us driving home without any doubts in a vehicle that can grow with my family. They were the cherry on top to an already excellent experience. Thank you from the bottom of our hearts for such a great team!

I had major work done on my car and I couldn?
I had major work done on my car and I couldn?t be happier with the turnout. I had my transmission replaced along with a couple other issues on my 2017 vehicle. It took a while for the entire thing to get completed, but I was given status updates throughout the process. I picked up my vehicle late last night (5:45 pm). I was surprised the service manager was still there and he took the time to go over everything that had been done to my vehicle. The total price was slightly lower than what I was I was told it would be at the start. I was very happy and wasn?t expecting that. My car is driving great today and so far I?m extremely happy with the result from my service experience. I?m very appreciative of the help I was given and the customer service I received. Thank you Justin and everyone who worked on my car. ?

Anthony greeted me in the parking lot and was friendly and professional. He quickly brought the car out that I wanted to see. Negotiations were very fair and the paperwork was done in a timely maner. I love my new/pre-owned HyundaiTucson. Thank you Anthony and the team! I'll see you again when I need my next vehicle.
