Owen and Austin did a great job once again sell me a 2025
Owen and Austin did a great job once again sell me a 2025 F150 Tremor. This is the 9th vehicle that we?ve bought from Ford of Murfreesboro. We also use their service department. Just 3 weeks ago my wife used their mobile service to come to the house and change her oil. I highly recommend the Ford of Murfreesboro team!
This truck has a jerk when changing gears sometimes.

Found truck online and connected with Jose.
Found truck online and connected with Jose. He and everyone were very friendly, and I appreciate Jose?s no-pressure approach. Initial numbers were much higher than advertised, but once pointed out we got to a good deal. Paperwork was no-fuss, but then again I brought my own financing.
Nicest, best performing truck I've ever owned
My truck has a great appearance, inside and out. It is a pleasure to drive; and rides and performs great. It is the best truck I've ever owned.

Be Sure to Ask Questions
Love our new car, but wasn’t told the CD player didn’t work .( info was not listed anywhere ) After purchasing the car we contacted them and were told they would not fix it. So my advice is shop there, but check everything carefully and ask questions.
2021 GMC Sierra Denali
This is the nicest truck I have ever owned. Lots of features. Takes a while to learn what all it does but a really enjoyable vehicle.

I’m not typically one to write reviews, but my experience
I’m not typically one to write reviews, but my experience with CarMax has been so outstanding that I feel compelled to share. From start to finish, they’ve redefined my expectations for buying a vehicle. I found a car online that checked every box for me—low miles, all the specs I wanted, and fantastic photos that gave me confidence in its condition. The only catch? It was located at a CarMax dealership in Florida, while I’m in Nashville. For just $200, they shipped it to my local CarMax dealership. Knowing the worst-case scenario was losing that $200, I felt reassured to take the leap—and I’m so glad I did. Within just a few days, the car arrived. I had a trade-in—a mid-mileage VW Atlas in good condition—and to my surprise, CarMax offered me an amazing price. I’ve done my research, and they gave me a value that was very close to what I’d seen comparable models selling for, and significantly more than I owed. Needless to say, I accepted their offer with ease. As for my new (used) car, I was impressed by the comprehensive warranty options. The extended warranty they offer feels like an insurance policy: $200 deductible for coverage up to 150,000 miles. With my car’s mileage at around 50,000, this was a no-brainer. I’ve seen glowing reviews about the warranty online, and after my own experience, I can see why. Now here’s the part that truly sets CarMax apart—the post-purchase experience. The vehicle is used, so it’s impossible to catch every little thing during a quick test drive. Thankfully, CarMax provides a 90-day warranty and has a full-service garage. I’ve been back a few times for small fixes, like the gas door not working properly, tire monitor sensors, an alignment issue, and even replacing a rear entertainment system screen. Every single issue was handled promptly and professionally, leaving me with a car that feels brand new. Shoutout to Elvis in the service department! Not only did he remember my name when I returned, but he also ensured I had a free loaner car anytime my vehicle needed to stay overnight. The customer service I’ve received from him and the entire CarMax team has been nothing short of exceptional. This entire process has been so seamless that I can confidently say CarMax will be my first stop the next time I’m in the market for a car. I’ve purchased brand-new vehicles before and never felt this satisfied. CarMax has raised the bar for what car buying and ownership should feel like. If you’re on the fence about where to purchase your next vehicle, I can’t recommend CarMax enough. From great trade-in offers to their stellar warranty program and impeccable customer service, they’ve won me over as a fan for life. Here’s hoping they stay around for a long, long time—because this is how car buying should be done.
Great Buy!
This truck is amazing. Turning heads all over as we tour the area. Those riding with is also enjoy the comforts and safety features. Great Buy!

Wilson County Chevrolet Buick GMC dealership is one of
Wilson County Chevrolet Buick GMC dealership is one of the best dealerships that I have been to in my 50 years of owning new vehicles. The facility is extremely clean, and the waiting area is one of the best. They are also very accommodating in scheduling a service call. Everyone from sales to service department are very nice and friendly. We even bring our grandchildren with us since they enjoy looking at the new models and they like the playroom. They even wash your vehicle after every service! We love it and thank you Wilson County Chevrolet for your continued great service.

great service
Thank you RYAN for a great experience getting my diesel ram fixed right! I came in thinking my clunking was coming from driveshaft U-Joints , But Ryan and his team were able to quickly get me in and properly diagnose and replace my front axle U-joints. While in there they also found one of the lugnuts I had repaired myself (incorrectly, thanks for the wrong part Oreilles!) and replaced it with the correct one. The wait wasn't too bad with the comfy and spacious waiting area, especially with the complimentary drinks and snacks on hand. Ill be back thanks to this positive experience at Beaman and the military discounts! Thank you for your support and quality service.

About 2 months ago I went to the dealership for an oil
About 2 months ago I went to the dealership for an oil change. Have an appointment at 11 o'clock in the morning. around 12 want to go see the service adviser asking where my car was at, he went to go To find out where my vehicle was at. It was still in the parking lot. All they had to say was they were sorry. I waited an hour and I had an appointment and nobody did nothing about it They haven't even started the oil change at 12 o'clock.
