We bought a Kia last week.
We bought a Kia last week. Trajce was so patient, kind and accommodating. He was very easy to connect with and trust. Once we decided on the right car, the sales process was so easy and fast. They were organized and got us back on the road quickly. We really love the car and would definitely recommend Trajce and Willowbrook Kia.
This truck has a jerk when changing gears sometimes.

My wife and I experienced a serious overheating problem
My wife and I experienced a serious overheating problem in our Santa Fe while driving from our home in Kansas City to Chicago. We found Kunes Hyundai online and were blown away by the superior service they offered. Kyle served as our service advisor, and he went above and beyond to take care of us. He patiently explained the problem, told us they had to order a part, and promised the vehicle would be done by Tuesday. When I left the facility, Kyle said he was on the phone trying to work a little magic to get the part sooner. I don't know who he called or what he said, but he worked the magic. The part came on Monday, and they had the Santa Fe fixed and back to us a day ahead of schedule! That was tremendous. We were already sold on the Hyundai, but this experience reminded us again of why we are on our third vehicle. The level of customer care is off the charts at Hyundai. And Kyle is the best service advisor we've ever had. The repairs fixed the problem and got us safely back home to Kansas City. I would gladly recommend Kunes Hyundai without hesitation. They are a five-star dealership! Check them out. You won't be disappointed! Ray Pritchard Shawnee, Kansas

David, made me feel welcome he's very friendly and informative. He answered any question I had and made the process of test driving and looking between 2 different vehicles easy and seamless. He treated me like someone he's known forever and even in a few moments of stress -nothing of which was their fault he let me take a few moments to myself and let me make a decision that was right for me. I appreciate his attentiveness. I would recommend anyone to come visit this location for great service. Thank you David.
