About Us

Our mission is to support classic car enthusiasts with quality parts, fair pricing, and knowledgeable service—helping keep Cadillacs, Buicks, Oldsmobiles, and Pontiacs on the road.

For more than 40 years, Caddy Daddy has been a trusted source for quality Cadillac parts, serving classic car enthusiasts around the world.

Founded by John “Caddy Daddy” Coyle, a lifelong Cadillac enthusiast, the company began with a simple belief: classic car owners deserved better access to parts and better service. What started as a personal passion grew into a business built on deep knowledge, craftsmanship, and genuine care for these cars.

From early days at West Coast swap meets and a mobile showroom to downloadable catalogs and an early online presence, Caddy Daddy has continually adapted to better serve its customers. Over time, the company expanded its inventory, built a dedicated team, and extended that same expertise to Buick, Oldsmobile, and Pontiac owners through BOP Parts.

Today, Caddy Daddy remains guided by the values it was founded on — quality parts, fair pricing, and knowledgeable, responsive service — supporting classic car owners now and for years to come.

Our Founder & Our Future

John built Caddy Daddy on knowledge, integrity, and a deep respect for the cars — and the people — behind every restoration.

After his passing, those values continue to guide how we operate and how we serve our customers. We are honoring what John built while strengthening the business for the next generation through better systems, expanded inventory, and a team-driven commitment to accuracy and service.

Cadillac remains at the heart of what we do, alongside a growing selection of Buick, Oldsmobile, and Pontiac parts. Our focus is simple: do the work right, support our customers well, and help keep classic cars on the road.
