Sam's Auto Shop on Chula Vista's Broadway handles general mechanical repair, brake-and-lamp inspections, smog checks, and A/C system diagnostics for domestic and import vehicles. The full-service bay covers suspension, engine, and electrical work that often precedes a tire swap, and drivers needing new rubber or alignment after a steering repair head to Hernandez Tire Pros in the same Chula Vista auto-service network. Brake-and-lamp certification qualifies the shop to issue the California safety inspection required for salvage-title vehicles being returned to road-legal status. Pre-purchase mechanical inspections at the 273 Broadway location serve buyers evaluating used vehicles from nearby lots, including inventory at Bahia Auto Sales, before finalizing a purchase. The most complex service calls involve R-1234yf refrigerant recovery, evacuation, and recharge on late-model A/C systems that require SAE J2788-compliant equipment and manifold gauges calibrated to 0.5-oz accuracy.
