In Placentia, shops are busiest on Monday mornings and before holiday weekends, so a mid-week appointment gets a car seen faster. Labor rates across California vary by neighborhood and by shop type, from small independents to dealership service bays, and mobile mechanics now cover many routine jobs in the driveway. Before authorizing a repair, ask for the estimate in writing, whether the shop warranties parts and labor (12 months / 12,000 miles is common, some offer more), and whether it can provide a loaner or a shuttle. Check the listing for hours, the makes the shop works on and its Google rating, then call ahead, since walk-in capacity is limited at smaller shops.
