We got a great car.
We got a great car. We have been to other dealerships and been very disappointed by their poor customer service. I did not know it was possible to have this great of an experience buying a car. All I can say is Rick was wonderful.
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.

This location is very good with customers, we bought two cars from this location, from sale manager down to sales lady both are great in helping my family. The only feedback, in terms facility, is pricing a Ford Dealership Pen ?? for purchase token of remembrance, especially the signing process, also the green tea bags were running out
Very comfortable to drive and relax in!
This truck was exactly what I was looking for! Great ride, and it will haul every thing that I need it to.! Low mileage without new car up front expense!

I went in last week to check out a 2019 Honda Accord
I went in last week to check out a 2019 Honda Accord EX-L, only because it was close to another car I was scheduled to test down the road in Pasadena. May sales rep was Mark and he's awesome. He is extremely helpful and knowledgeable and even better, showed me with minimal research that the other car I was going to see had TWO previous accidents (shame on me for not seeing that) and they met me at the price I needed. So I ended up buying the Accord (very low mileage) at a great price. The best part was how easy Mark made the experience. My wife is on the loan but she didn't even have to be there. I drove the car off the lot about 2 hours after I arrived. They let me keep my old Honda in the lot until we were able to return that afternoon to pick it up. Overall the best car buying experience we've ever had. Thanks Mark and JBA Auto!
In about 15 vehicle I had, this the best one
This truck just need nothing, comfort, strong, and beautiful, it's great for work, and for personal use, my next car will be the same but new

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.

My husband and I live in the Cincinnati area and found a new 2025 Yukon Elevation at Ron Marhofer for a great price. The price was as advertised online- no bait and switch with employee pricing or discounts that only certain groups qualify for- just a flat dealer discount. We worked with Steven and the process was smooth and easy- definitely worth driving 3.5 hours.

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.
