# How do I find an honest, trustworthy mechanic?

Look for a shop that is properly licensed (in California, every auto repair shop must be registered with the Bureau of Automotive Repair; check it on bar.ca.gov), gives you a written estimate before starting, asks before going over it, and will return your old parts. ASE-certified technicians and consistent recent reviews are good signs. AppointAuto lists repair shops by city with licensed shops first, so you can shortlist a few and compare quotes.

## Key facts

- In California, a repair shop must give a written estimate and get your approval before doing work or exceeding it.
- California shops must return replaced parts if you ask for them when you authorize the work.
- BAR registration can be checked online at bar.ca.gov.
