Our Story
M.G. Auto & Truck Repair started as a simple idea: offer honest, dependable service from people you can trust. Founded by Manuel Guerrero, a master mechanic with decades of experience, the shop was built on hard work, strong values, and a commitment to doing the job right the first time. What began as a one-man operation has grown into a family-run business that treats every customer like part of the crew.
Today, Manuel works side by side with his son, blending old-school know-how with modern techniques. Together, they bring a level of care and pride that’s hard to find in big chain shops. Whether you drive a compact car or a heavy-duty truck, you’ll get the same attention to detail, fair pricing, and real conversations from a team that stands behind their work because at M.G., your vehicle is family too.
