Our Reviews
Good dealership to work with. I just purchased a truck from them and they gave me the best price and didn't have any hidden fees. They also gave me the best price on my trade. Overall good experience.
Rachel was very helpful and very informative. The vehicle was serviced quickly and the wait didn’t last long. Overall a good experience.
Friendly and professional. Super clean waiting area and restroom. Free WiFi.
Best deal, zero hidden charges, no pressure. Other dealers had over $2,000 of extra fees and mandatory “protection” packages. None of that here.
Very nice and friendly their own time, and they keep the Word and do a good job. Thank you.
Just purchased a 2025 GMC Sierra 2500 HD from Beck and Masten GMC. Best car buying experience ever. Dominic Durrance in sales was great. He sold at the advertised internet price, gave me a good KBB value on my trade and did not try and pressure me into purchasing upgrades like extended warranties etc. I would definitely purchase from this dealership again.
Was very impressed with the Bernice that was provided! Everything was great. I will certainly be back and continue my business here
They very helpful on trying help me with my concerns
Sales staff was very helpful, friendly & polite. Service waiting area was nice. Financing wasn't as good as expected. None of the banks we have accounts with were contacted. Financing came back with over a 10% interest rate. I mentioned one of our banks for 5.99% and we did get that. I shouldn't have needed to ask.
This was the easiest auto purchase process I have ever had. Thank you to Tiffany Dubise in sales along with Melanie in finance for there attention to detail and holding beck on the normal car buying drama.
Rachel V is the best. I always receive personal care from her and she is very professional! I highly recommend B&M.
I liked that we were not pressured into buying. Dominic was very nice and respectful. Melanie was also very nice and polite. Very respectful. She was also very nice. They both covered our questions and answered them also. I would also recommend Dominic to our friends and family. I really appreciate everything they did and made us feel comfortable.
The staff was nice and helpful. My oil change & tire rotation was done quickly.i liked how they kept me updated through the text message.
Personal is friendly and easy to talk to. My truck is ready when they say and let’s me know if they need more time.
Easy to schedule with very prompt service
From beginning to end, the service and experience was exceptional. Our family traveled a few hours to the dealership and I appreciated the car buying transparency, quick service, and Richie’s support during the entire process. Richie was knowledgeable and took the time to go over every detail of our new vehicle. The dealership has gained a lifelong customer as a result. -Lozano Family
Robert Vasquez Always Takes Care Of Any Issues With my Vehicles With Great Communication And Service
Purchasing the vehicle was good. The service part of the deal was a wreck. Wrong parts ordered. Spent a whole day at the dealership just to find out they ordered the wrong bedcover. Had to take truck there again for another entire day and job wasn’t complete. Still isn’t. Bed cover isn’t mounted right and it makes a ton of noise when operating. Keypad still isn’t working and installed crooked
After numerous times of receiving poor service at one of the local competitors I decided to give this dealership a try. I’m glad that I did. Usually I’m able to get a same day appointment and while my vehicle is getting serviced there is constant communication on the stats of my vehicle with the service advisor. I’m glad I made the switch.
Great place! With amazing staff Everette and melanie are the best!!! The three vehicles i have gotten vehicles there i was never disappointed!
My service advisor Rachel always takes care of my needs while I'm there. And always keeps me informed on what's going on.
Rachel the service advisor was great . She worked with us to get us scheduled for diagnosing and then for repair. I love the communication. I understand being busy and having to wait for certain things to happen , but she really kept me Informed and went above and beyond with the scheduling as well . Great service and car was repaired rather quickly . Thanks to the mechanic as well .
Exceptional Customer Service…Mr. Rex Reynolds “Professionalism” was “Best of the Best”; along with Jesse, the Maintenance Technician and the Female Service Advisor who thanked me before I left the Department. Wish I could remember her name. True Dedicated Service Personnel
Helpful team members with a strong willingness to go the extra-mile for you and make the purchasing processs easy. Huge shoutout to Lisa Munro-Bechtold, Everette White, and Melanie Davis. Definitely would recommend from this location again
Rachel was amazing and very helpful during my visit. She kept me up to date on the work and timing.
