Billy was upfront and personable during the Palisade negotiations. No BS...I recommended him to my son during his Sante Fe negotiation. Billy located and brought in the vehicle he wanted.

New car buying made easy. The entire deal was completed through email and over the phone. Jason Davis was friendly and helpful. He answered my questions in a timely manner and made the experience simple and hassle free. The vehicle price was straightforward with no haggling required. I felt like I received a very fair trade in on my truck.

I recently purchased a car from this dealership, and I cannot say enough how wonderful the experience was! From the moment I walked in, I was greeted with a warm and friendly welcome that immediately put me at ease. Every step of the process was smooth, straightforward, and stress-free. The customer service here is nothing short of fantastic. The staff was knowledgeable, patient, and truly seemed to care about helping me find the right vehicle. Special thanks to the general manager, Scott, who went above and beyond to make sure everything went as smoothly as possible. He made what can often be a stressful experience feel easy and enjoyable. I would highly recommend this dealership to my family and friends because I know they would have a great experience, just like I did.

As a woman who honestly knows nothing about cars, I was nervous that I was going to be conned into things I didn’t need. I was lucky enough to have Mike help me who was extremely professional, friendly, and explained in detail what I needed now and suggestions for services repairs that were not needed immediately. I never felt pressured but ended up doing everything. There is no other dealership I will use in the future!
