From the business
In the shop's own words: “A Family-Run Shop Built on Trust”
Diamond Auto Center is a family-run shop in Ontario, run by Rick and his son alongside a team that includes Mikey, Scott, Marcos, and Brian. Customers keep coming back because the diagnosis is honest, the pricing is fair, and the work gets done right the first time.
We treat every car like it belongs to family. When one customer accidentally left her wallet in the glove compartment, it was still there, untouched, when she picked up her keys. That is the standard we hold ourselves to on every job, from a flat tire to a full diagnostic.
Whether you need a quick tire fix or a deeper repair, we walk you through what is wrong, what it costs, and get you back on the road quickly.
- Family-owned shop
- Transparent, fair pricing
- Same-day tire repairs
- Trusted across the Inland Empire
