Tim Clark and Ray Bennett from LEADCAR GMC, made the process of buying my truck completely seamless. They went above and beyond, supported and facilitated my search for the vehicle l wanted, decision making, and the paperwork, seamlessly. They also helped my close friend with his first-ever GMC brand-new truck, and gave him a deal that made one other local GMC competitor?s deal look like a highway robbery! They are a great team and an absolute asset to LEADCAR. This was my 3rd GMC AT4!
So far so good!
So far so good! This truck is the nicest truck I have ever driven. The stance, ride comfort and options are top notch. I went from a 2023 High Country that was having drive train issues but had all the creature comforts that you would expect in a top of the line truck. With the lack of confidence in that particular models 10 speed transmission issues, it became necessary to reestablish my confidence in my General Motors product.
