Mr. Mike Buhler at Lenz Truck Center
I had the distinct pleasure of having the opportunity to work with Mr. Buhler on the purchase of my 2022 GMC Yukon Denali. Within minutes of submitting my request for information on the vehicle, Mr. Buhler contacted me. He provided me with all of the information I needed to make my decision, which was one of the easiest decisions I have ever made regarding the purchase of a vehicle. I drove over 12 hours to pick up my Denali and Mr. Buhler was waiting for me at 7:30 AM the following day to hand me the keys. This experience was far and away the absolute best vehicle purchasing experience I have ever had! Thank you, Mr. Buhler!
This truck has a jerk when changing gears sometimes.

My car started making a noise, and I was planning on taking it out of town. I took it to the Service Department before leaving and worked with Brian. Brian was a true gentleman and simply AMAZING! He listened to my concerns and made sure the issue was fixed. I am so blessed to have worked with Brian. Thank you, Brian!

I showed up without an appointment because I was in the area. Asked the young man at the entrance to the oil change building if they had any room to fit me in so I could have my transmission flushed with filter change (as recommended in manual due to the new style transmissions being a ?sealed? unit) as well as an oil change. He got me in later in the afternoon. I was in the waiting area only an hour for everything to be done. Pop and coffee available at no charge. Comfortable seating as well as a television. Very relaxing really.

Hi Gary, I cannot say enough about your Company.
Hi Gary, I cannot say enough about your Company. This is the second truck we have purchased in the last year. The sales, (Paul), and the support, (Sue Peterson), staff are second to none. They were very honest and helpful. They were extremely patient with my Wife and I, (mainly me), while we were picking out different vehicles. They were very upfront about pricing and not the usual back-and-forth pricing game played at many other Dealerships. I truly appreciate the sense of Family within your Company. It does resonate well with us, your customers. Thank you, Jerry and Julie Schiefelbein
