My wife, son, and I had a wonderful experience.
My wife, son, and I had a wonderful experience. H�ctor, who assisted us throughout the process, was extremely kind and professional. He showed us the vehicle options we were looking for and worked to get the monthly payment as close as possible to our budget. There was absolutely no pressure to buy at any moment, and he was patient while we made our final decision. We definitely recommend him to family and friends who are looking to purchase a vehicle.
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!

I bought a 2024 used mini convertible from MINI of the Woodlands. I live 1400 miles away in Virginia but Nathan Smith made it as easy for me as was possible. Nathan had great suggestions and answered my emails, texts and calls quickly- even on his day off. He even picked me up from the airport. The payment and pickup was simple and no pressure for extra add ons. I love the car and was impressed with Mini of The Woodlands.

Martin Chevrolet Buick GMC, Cleveland, Texas
I seriously have too much to write in a review about my experience over the last 4 year of trying to purchase this new vehicle. But I am going to forego all that and get to the point?. I have just taken delivery of a new a 2023 GMC Sierra 1500, Denali, 4WD, Crew Cab-Short Box purchased from Martin Chevrolet Buick GMC, 420 W Southline Street, Cleveland Tx 77372 281-761-7029. Martin Chevrolet Buick GMC is a Family own busine run This purchase makes my 5th Special order vehicle I have purchased in my life. Each and every time, I sat down to do the numbers, you leave the dealership with your head spinning as to the stuff they try to incorporate into your Sales Agreement. NOT this time, Martin Chevrolet Buick GMC did everything that I was expecting. First, let me tell you I had the Dream team working on my behalf. Shout out to; Janet Martin- Vice President, Efrain Salazar ? Sales Manager, JC Phillips ? Finance Manager and MOST important; Justin Allen ? Sales Specialist who work with me for over two years to get my new vehicle. The amount of time to get the vehicle was of no fault of this dealership, it was General Motors, Covid, Part Shortages and anything else you can think of. However, Justin Allen, walked that walk with me to make sure I was up to date on all information I needed. He listened, he heard and he was there every time I had a question, worry or concern. Thank you Justin Allen. On May 15th, I got a call from Justin saying your new truck has just arrived, come on up and get it. Of course, we went thru all that sale process at this time and I can tell you I was not pressure and being a numbers guy, all their number was what I had gone in with. The Sales manager made she I was okay with the numbers and the Finance guy did not beat me over the head trying to sell me things I didn?t want. Note: this was my 4th order of this new vehicle, twice before with different GMC dealerships who at the end of the process was inflating their number much more than I was going to do. What I can tell you about Martin Chevrolet Buick GMC is that they CARE about the customer and are will to work with you to make your Dreams come true. Thank you, Thank you, Thank you?. Thank you Justin Allen. Respectfully, MRPHIL 05-24-2023
