Our story
The Shop Drivers Trust on Main Street
We're Cali MJ Auto Repair, a car repair and maintenance shop at 3707 Main Street in Los Angeles. Drivers come to us for exhaust and muffler work, radiator repairs, fuel tank cleaning, and everyday maintenance, and they keep coming back because we give straight answers and fair prices.
Our customers say it best: they call us honest, informative, and easy to work with. When a part isn't in stock, we track it down. When a radiator gives out over a holiday weekend, we make room for the car. That's just how we do business.
We're open Monday through Saturday, 8:00 AM to 5:00 PM. Bring your car by, or give us a call. We'll tell you exactly what it needs and what it will cost.
