Most Perth mechanics are honest professionals who do good work at fair prices. A small minority aren't — and their tactics are consistent enough that once you know what to look for, they're recognisable. Here's how to protect yourself.
Warning Sign #1: Quote Creep
You bring the car in for a specific job. The mechanic calls you and says they've found several additional problems that also need urgent attention. This happens to some extent with every vehicle — but watch for the pattern of discovery. Legitimate additional work is explained clearly, with a written quote for each item and no pressure to approve immediately. Dishonest mechanics use high-pressure tactics and vague descriptions to get you to approve additional work while you're on the phone.
Warning Sign #2: Not Showing Old Parts
When a mechanic replaces a part, they should offer to show you the old part upon request. If they won't — or if the old part looks suspiciously new when you see it — that's a concern. Ask to see what was replaced.
Warning Sign #3: Urgent But Vague
A mechanic who says "it needs urgent attention but I can't really explain it simply" is a red flag. Qualified mechanics should be able to explain in plain terms what's wrong and why it needs fixing. If the explanation is vague, ask follow-up questions until it's clear — or get a second opinion.
Warning Sign #4: No Written Quote
A reputable mechanic always provides a written quote before starting work. A mechanic who won't commit to a price in writing is creating an environment where the final invoice can be whatever they decide after the work is done. This isn't acceptable — it's also contrary to WA consumer law requirements.
Your Rights Under WA Consumer Law
- You have the right to request a written estimate before authorising work
- Mechanics must contact you if the cost will exceed the estimate by a significant amount
- Work must be of acceptable quality and fit for purpose
- You can dispute an invoice that significantly exceeds the authorised quote
What to Do If You Think You've Been Overcharged
Request an itemised invoice. Compare it against the original quote. For any item significantly above the quote, ask for an explanation. If you're not satisfied, contact Consumer Protection WA — they handle complaints about motor vehicle repairers. You can also pursue disputes through the State Administrative Tribunal.
