About GM Service Guy

Welcome to GM Service Guy — your trusted source for genuine GM parts, service tools, and automotive accessories. My name is Allen McCormick, and cars have been my world for nearly two decades.

My journey with General Motors began back in 2007, when I started my career in sales at Chevrolet dealerships in Saskatoon, Saskatchewan. For over a decade, I had the privilege of helping customers find the perfect GM vehicles — from hardworking Silverados to family-friendly SUVs — while learning the ins and outs of GM's engineering, reliability, and craftsmanship.

In 2019, I continued my passion for the brand in Las Vegas, again selling GM vehicles and building lasting relationships with customers who share the same passion for quality and performance. That same year, I took my experience from sales to the service side of the business, joining Findlay North Volkswagen as a Service Advisor. There, I deepened my technical knowledge and learned the value of honest, professional customer care when it comes to vehicle maintenance and repair.

Since 2021, I've been proud to serve as a Service Advisor at Fairway Chevrolet, continuing my commitment to keeping GM owners confident in their vehicles every time they drive.

Through GM Service Guy, my goal is simple — to make it easier for GM owners and enthusiasts to access the reliable parts, accessories, and tools they need, backed by real automotive experience. Whether you're maintaining your own GM vehicle or customizing it for performance, I'm here to help you find the right products and support every step of the way.

Trusted experience. Genuine parts. Real advice — from someone who knows GM inside and out.
