New and used 2026 GMC Sierra 1500 trucks for sale near Wheaton, MO

My salesman Chuck was outstanding and very patient with me. As a single lady car shopping I was very comfortable with him and he was so respectful. Austin was my finance person and he was also outstanding. Both should be highly praised for their outstanding service.

This is just about the only dealership in my area that I enjoy going to and always leave very satisfied. I always ask for John K., most professional salesman I’ve ever met!

I was absolutely amazed at the professionalism of the staff at Mayse. William and Stan were so accommodating but not pushy. I would recommend them to anyone and definitely will be back. Thank you for such a pleasant car buying experience

Yesterday I gave a very negative review. I should have waited. Today I had a call from Ryan the Service Manager and he understood my my frustration. After talking I found out he had been the Service Manager at the Dealership I had used for 10 years before I bought my Renegade. Now I have confidence all will be OK. If anyone has had a bad experience like I had give him a chance to fix the problem, I am sure you won't be disappointed.

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!!

Ehren and Laz were great to work with from start to finish. We experienced top notch service with no pressure to buy. We took off work to come to Aurora and appreciate their prompt attention and being ready when we arrived. Also enjoyed the conversations while there. Get to know Laz and Ehren, you won’t regret it.

Lee was fantastic to work with and was a wealth of information. The experience was quick and didn?t feel like a waste of my time.

My experience was Low pressure, courteous, informative. Tyler provided a great service, even after hours to keep me informed. New truck purchase was made easy.

As usual, great service and experience, Had my 2019 Buick Enclave's oil changed and tires rotated. Will definitely consider McClarty Buick when looking to trade vehicles in the future.
