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
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.
