I had the best experience I’ve ever had purchasing a vehicle. Billy, the sales rep was very informative, patient and kind. Daniel in finance was very thorough in his explanation of warranty and additional benefits. Overall, excellent service from everyone.
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.

I purchased a 2025 Mazda cx70 with the help of Kenneth at Boucher. He wasn’t pushy and actually made the whole car buying process a little less terrible! The manager was also willing to work with me on numbers to suit my budget. If you’re in need of a Mazda, ask for Kenneth!

Excellent Service all the way around.
Excellent Service all the way around. Maintenance was completed in a very timely manner. My initial appointment wasn't until 10:30 am. As I did not have any particular things going on so dropped it off at 8:30 am and told them that they could keep it as long as necessary. I received a call at 9:30 am stating that all maintenance had been completed, an our before my scheduled appointment.

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.
