ASE-certified master technicians have anchored Rob's Automotive on El Cajon Boulevard in La Mesa since 1996, covering brakes, transmissions, electrical systems, and custom exhaust fabrication. Collision-related mechanical work — bent subframes, damaged steering racks, misaligned suspension geometry — often arrives as referrals from neighboring body shops including Davey Auto Body on the same corridor. The shop builds custom stainless-steel exhaust systems for performance cars, classics, 4x4s, and racecars, bending mandrel pipe and welding headers in-house. Transmission services range from fluid-and-filter changes to full rebuilds on both automatic and manual gearboxes, with driveline inspections covering CV joints, U-joints, and differential seals. Each completed vehicle receives a post-service wash and interior wipe-down through mobile providers like Walker's Mobile Detailing before customer pickup. Highest-tier jobs involve custom performance exhaust fabrication with mandrel-bent stainless tubing, requiring back-pressure flow testing, weld-penetration inspection, and catalytic converter placement to CARB-compliant specifications.
