Had the pleasure of having Nick Majeske provide us with an unbelievable experience of buying a new car. From start to finish and even after we purchased our car, his support and genuine desire to make sure we were satisfied did not go unnoticed. What really stood out to us was throughout the process, Nick was transparent and honest, which I greatly appreciated. He kept us informed every step of the way, and there were no surprises or hidden fees. His professionalism and integrity are truly commendable. We could not be happier with our purchase and overall experience throughout it all, and we would like to think this was in all thanks to Nick.

Turned into a great visit
Thank you so much for a great experience. Chad, the salesman, that I worked with was great. I was a bit nervous before coming in this morning due to my daughter's experience with a salesman at the Kunes next door to this one. But it quickly became a great visit. He was patient and did everything he could so I could drive the car off the lot today. Everyone was very helpful and friendly. He also promised to get me a manual for the Hyundai Tuscon I bought that is missing. I hope he keeps that promise. The salesman, Roel, who was the one next door that my daughter had was not so good. He was demanding and was not very truthful. I believe that he would sell anything or say anything just to make a sale. He demanded that I get in there to cosign for my daughter for a car that was way over her means. Cosigning for someone is a very huge thing and should never be demanded even by a salesman.

Excellent service
Anytime I call and let them know that there’s a problem with my vehicle I bring it in and they take care of it. Found out yesterday that there’s something wrong with my transmission. Thank God for their warranties. I have a special needs son and I need a bigger vehicle and because of them I have that bigger vehicle.
