Advanced Auto Tech in downtown San Diego's East Village holds ASE certification and STAR-designated smog-station status, running test-and-repair inspections from 301 16th Street since 2000. The STAR tier means California's Bureau of Automotive Repair audits the shop's pass/fail data against statewide benchmarks, qualifying it to certify directed vehicles and gross polluters — emissions-critical work that often follows collision-repair teardowns at Fix Auto Downtown SD on nearby Market Street. Honda, Acura, Toyota, and Lexus make up the core specialization, with factory-pattern diagnostics for VTEC valve-timing systems and Toyota's D-4S direct-injection engines. Windshield chips and seal failures caught during pre-smog visual inspections route to WindshieldHUB for mobile glass replacement that keeps the vehicle on its certification timeline. Full transmission rebuilds and radiator-core replacements anchor the heavy-mechanical side of the shop, pulling complete drivetrain assemblies in the same 16th Street lift bays that run five-minute smog certificates.
