About Us
at Shelton Automotive Group

Shelton Automotive Group & Diesel Repair is a natural extension of a vision that started long before the service bays were built or the lifts were installed. Our dealership opened in 2022 with Grant Shelton at the wheel, and in 2025 we expanded into a full-service repair shop to better support our customers and their trucks. From the beginning, Grant wanted to build something more than a place to buy a vehicle, he wanted a destination drivers could trust for every mile ahead.

A Shop Drivers Can Count On

Around Warrenton and the surrounding communities, it’s tough to find a shop that truly understands light-duty diesel trucks and the aftermarket upgrades that make them stand out. We’re one of the few teams in the area that not only services diesel engines, but also installs lift kits, leveling kits, and performance modifications with precision. Our customers come to us because they know they’ll get straight answers, skilled hands, and results that speak for themselves.

The Passion Behind the Business

Grant didn’t start out looking to run a dealership or a repair shop. He started with a genuine love for trucks, how they’re built, how they work, and how the right one can change a person’s workday or weekend adventures. That curiosity grew into a commitment to offering reliable vehicles and honest guidance. No tricks, no pressure, just transparency and respect. As word spread, it was clear there was a need not only for trustworthy truck sales, but also for trustworthy diesel repairs, and the shop was born.

A Team That Shares the Mission

Walk into our service department and you’ll meet a group of people who show up ready to do things right. Our employees aren’t just here to punch a clock, they take pride in the work they do and the customers they help. They know how important it is to get repairs right the first time, communicate clearly, and make sure every driver leaves feeling confident about their truck. That integrity is what shapes our reputation and keeps our customers coming back.

Life Outside the Shop

Running a business takes focus, but Grant still makes time for the things that keep life fun. When he’s not at the shop, you’ll probably find him racing motocross or spending a day on the golf course. Those moments refuel him so he can continue growing the business and supporting the people who depend on it.

Family at the Core

Behind every late night, every early morning, and every milestone, Grant’s family has been there. Their support is the foundation beneath everything we do here and a reminder of why this work matters. Building this business hasn’t just been a professional journey, it’s been a family one, and we’re proud of the legacy it continues to build in our community.
