Meet our Team of Diesel Specialists

Kevin McCary — Owner and General Manager Kevin McCary is the Owner and General Manager of North Texas Truck Stop, bringing over 40 years of experience in the automotive industry and a deep, three-generation legacy in the car business. His family entered the industry shortly after World War II, drawing on the mechanical expertise his grandfather gained while serving in the military. That foundation grew into a family tradition of technical excellence and customer service. Kevin’s father became a Mercedes-Benz diesel specialist, serving discerning customers and dealerships across the country at a time when nationwide service networks were nearly unheard of due to limited communication technology. That pioneering spirit and commitment to diesel expertise shaped Kevin’s own path in the industry. Kevin began his career in the European car wholesale market, gaining extensive experience in vehicle sourcing, evaluation, and dealer operations. In 2006, he transitioned into diesel-specific vehicles, applying his generational knowledge to build one of the region’s most respected diesel inventory operations. At North Texas Truck Stop, Kevin oversees all executive functions, diesel inventory acquisition, and corporate finance, ensuring every truck meets the high standards the dealership is known for.
