Adam Winfrey at Crain Kia Bentonville was great helping
Adam Winfrey at Crain Kia Bentonville was great helping me get scheduled for the very next morning when I came in a little frantic about all of my headlights suddenly not working & also scheduled me to have my 30K mile service done at the same time. So thankful he was able to arrange a driver to take me home during the 3-4 hour service and pick me back up when my car was ready. Even better, my car was vacuumed and beautifully washed waiting for me. That was a great surprise! Especially after my last service at Crain Kia Fayetteville not going well at all. So bad I swear I would go back… I truly appreciate Crain Kia Bentonville’s excellent customer service, attention to detail and going above and beyond to ensure I felt safe leaving in my vehicle after my Fayetteville service left me a little traumatized. Thanks again Adam!!!

I went to MD Buick GMC a couple of months ago to inquire
I went to MD Buick GMC a couple of months ago to inquire about purchasing a 2025 Hummer EV SUV. We discussed several options and the staff was extremely knowledgeable about EVs, especially the Hummers. Cole (sales rep) was amazing to work with! Great guy! Passionate about what he does and truly cares about his customers! Grant (sales manager) actually took us on a test drive of the SUV to better inform us of its capabilities! The test drive was a blast! He took his time to answer all of the kids questions, was patient and really made everyone feel a part of the process! When we got to the negotiating, Todd (GM) made sure that we got the best deal possible! He was super easy to work with, made sure we understood everything, and got exactly what we wanted. Austin (Finance) took great care of us as well! Again, made sure we got everything we needed, went over all the numbers again to make sure nothing was missed, and helped us get all the coverages we needed/wanted! Ryan (service manager) was extremely helpful in making sure we got the accessories we needed, like a home charger! He was super informative, and took great care of us! Everyone was truly amazing to work with throughout the entire buying process! The next time I am looking for a vehicle, I will absolutely go back and let them help me find the vehicle I want! I wish every dealership conducted themselves as these guys do! I would probably buy cars more often! I almost forgot the best part!! It didn?t take all day to buy a car!! They were very respectful of our time, took the time needed to ensure we were extremely happy, got exactly what we wanted, and made the process as efficient and painless as possible!! It was truly the best car buying experience I have had! The whole family loves the new Hummer EV SUV!!
