I have brought my vehicle in for every oil change I have
I have brought my vehicle in for every oil change I have needed. Always courteous and professional, my car gets a diagnostic check every time and is freshly washed. I like that the Service Department send out coupons, and making an appointment is easy online or with a phone call.

Mr. Dixon was easy to work with. He was fair and gave us more for our trade than I know it was worth. I gave him 5 stars, but he deserves double that. Well run dealership.

We really appreciated how dedicated the staff at Huntley
We really appreciated how dedicated the staff at Huntley Ford were. We spoke on the phone and visited to check out a few vehicles with Daniel. He was very patient and wonderful to work with. Although we didn't purchase a car during our visit, we would recommend that anyone visits the dealer for a great experience.

After purchasing more than 20 new cars over the years, I
After purchasing more than 20 new cars over the years, I can say without hesitation that my experience with Wickstrom Automotive Group was the best car-buying experience I’ve ever had. What made this experience truly exceptional was the care and professionalism shown not just to me, but to my son as he purchased his first car. The entire team went out of their way to turn the process into an educational, confidence-building experience for him—something I genuinely appreciate as a parent. I want to specifically recognize Eric Jensen, Sales Professional, who was patient, knowledgeable, and generous with his time, walking my son through every step of vehicle selection and the sales process. Chris Moose, CDJR General Manager, exemplified leadership and professionalism, ensuring everything was handled smoothly and transparently. And Colin Wickstrom, Owner, reinforced why this organization operates at such a high level—his involvement, friendliness and commitment to customer experience clearly set the tone for the entire group. From start to finish, there was zero pressure, clear communication, and a refreshing level of honesty that’s rare in today’s automotive market. Wickstrom Automotive Group treats customers like long-term relationships, not transactions and dare I even say my son and I had a ton of fun throughout this process. If you’re looking for a dealership group that sets the gold standard for how car buying should be done—especially for a first-time buyer—I give Wickstrom Automotive Group my strongest recommendation.
