Gene Messer Ford of Lubbock review
We drove 5 hrs to purchase our vehicle and it was well
We drove 5 hrs to purchase our vehicle and it was well worth the drive. We bought a used car and we were treated like we won the lottery and we’re buying a dozen new ones!! Brad Arrington was the best! Everyone we dealt with was top notch. Who knows, someday we may drive 5 hrs just to come back. The Browns Gainesville Texas

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.

Find Rick. Seriously, these folks are good, but Rick is great. Find Rick, ask him for help. Even if you walk away without a car, you'll have had the best possible shot at a great deal with great service with Rick. Find Rick.

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.

Kuehn Motors review
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.
