Perth has hundreds of mechanic workshops, ranging from excellent to genuinely problematic. The challenge for drivers is that it's hard to tell the difference until you've already handed over your keys. Here's how to evaluate a mechanic before trusting them with your vehicle.
Check Their Licence
In Western Australia, mechanics performing vehicle repair work must hold a Motor Vehicle Repairer licence issued by Consumer Protection WA. This is non-negotiable — it's a legal requirement. You can verify a mechanic's licence online through the Consumer Protection WA website. If a workshop can't or won't confirm their licensing, walk away.
Look for Genuine Reviews
Google Reviews are a reasonable signal for mechanic quality — but look at the pattern, not just the star rating. A mechanic with 40 genuine reviews averaging 4.7 stars is more reliable than one with 200 reviews averaging 4.9 (which can indicate managed reviews). Look for reviews that mention specific work done, honest assessments, and follow-through on quotes.
Get a Written Quote Before Authorising Work
A trustworthy mechanic always provides a written quote before starting work. Under WA consumer law, mechanics are required to provide an estimate upon request and cannot charge significantly more than that estimate without contacting you first. If a mechanic won't quote before starting, that's a significant red flag.
Questions to Ask Before Committing
- Are you a licensed Motor Vehicle Repairer?
- Can you provide a written quote before starting work?
- Do you use genuine or OEM-equivalent parts?
- What warranty do you provide on your work?
- Will you show me the old parts if you replace something?
Red Flags to Watch For
- Won't provide a written quote upfront
- Quotes low, then discovers additional problems once the car is pulled apart
- Pressures you to approve additional work immediately without time to consider
- Can't explain clearly what work they found is needed
- No fixed address — pop-up mechanics without a verifiable business location
