From the business
In the shop's own words: “A neighborhood garage that does the job right”
At T-21 Auto Services and Repairs, we believe you should only pay for the work your car actually needs. That's why we test before we replace — customers know us as the shop that doesn't just throw parts at a problem, whether we're tracking down a leak or confirming a catalytic converter really is at the end of its life. From our garage at 4049 3rd Street in San Francisco's Bayview, Joe and the team handle everything from oil service and spark plugs to radiators, alignments, and emissions work — and we're known for keeping older cars running smooth for years. Fair pricing, straight answers, and repairs that hold up: that's what has earned us a 5-star rating across 140 Google reviews. We're open six days a week and happy to take walk-ins. Stop by or give us a call — we'll give you an honest assessment and get you back on the road.
