New and used 2025 GMC Sierra 2500 trucks for sale near McLendon-Chisholm, TX

They say the most loyal customers come from ones who have an issue and the company makes it right, even if it wasn?t their fault. This couldn?t be more true with the service department at McKinney GMC. They took an issue that was not their fault, and fought alongside us to get it rectified and ensure a positive outcome for us and I will be forever grateful for John, Rob, Amanda, Caleb, and Victor for putting in the extra work to help get this resolved successfully. We just picked up our vehicle after it being in service for 5 months, to no fault of the dealership, but due to an issue with the insurance adjuster. Our vehicle had shut down due to what was later determined to be contaminated fuel, but the insurance adjuster made a mistake in his findings, and denied it. The service department answered every question, provided every document, picture, and detail I requested as I was fighting this with insurance, and let me tell you, I requested a lot. And they did it with grace, even on the days I sat in their dealership for hours on end collecting things. We had also contacted GMC/GM customer service and the McKinney service department did all they could to work with them, and helped us to have the claim resubmitted to insurance. After a long and painful process, we finally have our vehicle back, insurance rightfully covered the work, all because of the dedication of this team. McKinney GMC will have a customer for life in me. Thank you again team for all you did!

They did it all, the experience speaks for itself, perfection, only way it could have been better is if it was closer to my house and free, thank you much!

Forest, our sales representative was an amazing man. He was very professional and knowledgeable. He was also very friendly and went out if his way to make sure we knew all about the vehicle we were interested in purchasing. He went with us so I could test drive the car and explained all the features and how to work them . Forest even took me around the dealership and introduced me to various employees, showed me where the service and parts departments were and, once again introduced me to the people in those departments. He also showed me where the customer lounge and vending area was along with the free coffee area. Forest introduced me to the finance person who would be serving me. On a scale of 1 to 10, I would rate Forest a 12. Outstanding! Thank you Forest, Ralph Larry Malone
