Family Run for Four Generations

Two men smiling and standing close together outside a building decorated with numerous vintage license plates. One man has a shaved head and a goatee, and the other has short brown hair and a beard.

Four Generations.
One Mission: To Keep You Moving.

Merwin Auto has always been more than just a repair shop—it’s a family legacy. Now in its fourth generation, the business is proudly run by Ron Wightman, great-grandson of founder Bob Wightman. We cherish and miss Chris Wightman, Ron’s father who recently passed. You could always find him lending a helpful hand (and flashing his trademark smile). His brother Jeff—Ron’s uncle—continues to be a trusted voice behind Merwin’s reputation for honest, reliable service.

What began as a small gas station offering oil changes and tire repairs has grown into a full-service auto repair facility trusted by generations of local drivers. As the industry has evolved, so have we—earning certifications, expanding our services, and adopting new technologies, all while staying true to the values we were built on: quality work, fair prices, and service with integrity.

Built on Legacy. Driven by Community.

We’re proud of the recognition we've received over the years from our township, state, and local business organizations—but what matters most to us is the continued trust of our community. Giving back is part of who we are, whether it’s through local charity work, volunteer efforts, or simply going the extra mile for a neighbor in need.

At Merwin Auto, you’re not just getting your car fixed—you’re joining a family that’s been serving this town with heart for over 65 years.
