Driven by quality.
After years in the industry, Justin wanted to apply his expertise in his own aftermarket shop to provide customers with quality repairs at reasonable prices. So he got creative, and he and his wife Sarah bought a decommissioned fire rescue truck and transformed it into a mobile service unit right in their driveway.
