“If you're looking for reliable, honest, and affordable auto repair in National City, look no further than Diamante Auto Repair. They're a true one-stop shop, handling everything from mechanical repairs and oil changes to full collision and auto body work. After an accident, I didn't have to visit two different shops.

“Mechanics are great and funny and they specialize in all makes of cars, luxury cars, imports, etc. They get the job done. The owner is great and reasonable on prices with dealer quality work. They fixed my Honda CRV to pass smog when no other mechanic could. Great job!”
“The owner of Diamante Motors was a very cool dude who got my car fixed under my warranty even though the place that was supposed to cover it was trying to duck out and not cover it. That place is a great shop and I would definitely recommend them to others, and for sure going back when I need repairs.”
