I bought the vehicle online without ever seeing it in person. Easy transaction. Great financing and smooth delivery!
A Beast when it comes to hauling!
I love how the truck pulls and rides when towing. It will give any driver the confidence to tow anywhere. I haven't had a single issue with it. I love the way it looks and couldn't be happier.

Great Experience
Chase was awesome to work with. Single mom looking for a car for her teenage daughter. We had experienced “mansplaining” and driving a long distance only to find a defective car (Bunker Lake Motors), so I asked a bunch of questions before we went to see the car at Kuehn Motors. Chase was very patient and answered all that he could and found out the answers to the ones he couldn’t. Once we got there, the car was exactly as Chase had described it, actually even cleaner than we had expected. The whole process was easy and no surprises or pressure.

This was the best customer service we have received. They did not have the exact truck in stock so they ask if they could look around and locate what we wanted. They located the exact truck and did a dealer trade. Great buying experience. everyone we dealt with was awesome.

Every person involved in the engine replacement of our
Every person involved in the engine replacement of our family truck should get some sort of bonus and/or recognition for saving our family vacation. They somehow pulled enough strings to get my new engine ordered, shipped, installed, and my truck back to me in about 2 weeks. That allowed us to have a vehicle large enough to tow a boat and have 4 adults comfortably riding down the road.

We went by to look at one car but it was out for repairs. Our second choice was available so we took it for a test drive. We were so pleased with the salesman, Amir, who was so calm, helpful, and honest with us about our car options. We thanked him for facilitating such a chill car buying experience.
