Reading the quote
How to break down a repair quote into parts you can verify
The real issue
The information asymmetry in car repair is real — most customers don't know what things should cost, which makes overcharging easy. The remedy is not distrust — it's asking the right questions. A mechanic who can't or won't itemise their quote, provide part numbers, or explain their labour hours is the problem. Most good mechanics welcome informed customers.
| Quote component | How to verify it |
|---|---|
| Parts — price | Ask for the part number (OEM or aftermarket). Search the part number on repco.com.au, supercheapauto.com.au, or the manufacturer's site. The mechanic's price will be above retail (that's their margin — reasonable), but 2–3× retail price is worth questioning. |
| Parts — OEM vs aftermarket | OEM (Original Equipment Manufacturer) parts are made by the car manufacturer or their supplier. Aftermarket are third-party alternatives — cheaper but variable quality. Ask which is being used and whether you have a choice. |
| Labour hours | Standard repair times are set by manufacturer guides (used by insurers and dealerships). Ask: "How many labour hours are you charging for this job?" Then search "[make model year] + [repair job] + "how many hours"" to get a sense of industry norms. More than 20% above standard is worth discussing. |
| Labour rate | Quoted per hour. Varies by region and shop type: dealerships $150–$250/hr; independent specialists $100–$180/hr; chain workshops $80–$130/hr. Ask for the rate if not shown. If it's not itemised at all, ask for an itemised quote before approving any work. |

Red flags
Patterns that suggest overcharging or unnecessary work
| Red flag | What it may mean |
|---|---|
| Refusal to itemise | "It's just one price" — reputable shops always provide itemised quotes. Non-itemised quotes make it impossible to verify any component. |
| Urgent pressure to approve additional work | "We found more problems while we were in there — needs to be done today or it'll cause engine damage." Legitimate additional findings are real, but pressure tactics without written documentation warrant a second opinion. |
| Return of replaced parts refused | Ask to see the old part when you pick up the car. If a mechanic replaced your brake pads, you should be able to see (and keep) the worn pads. Refusal suggests the work may not have been done. |
| Verbal quote significantly lower than written | Always get the quote in writing before authorising work. A verbal quote of $300 that becomes a $700 invoice is a dispute — a written quote limits that exposure. |
| Recommended interval far shorter than manufacturer's | If a mechanic recommends a service interval significantly shorter than the manufacturer's manual specifies (e.g. oil changes every 3,000km when the manual says 10,000km), ask them to show you where the manufacturer makes that recommendation. |
Always get the quote in writing before authorising any work. In Australia, under ACL you are entitled to a written quote for work above a threshold (varies by state, typically $50–$150). If the final invoice exceeds the written quote by more than 10%, you can dispute the excess.

Getting it checked
When and how to get a second opinion
A second opinion is warranted when: the quote is significantly higher than expected, the recommended work seems extensive or unexpected for the car's age and mileage, or the mechanic is recommending replacing something that was recently serviced elsewhere.
| Situation | Approach |
|---|---|
| Car is driveable | Ask for the written diagnostic report, take the car, and get a second quote at a different shop. Show them the first quote and ask them to price the same job. |
| Car is not driveable (at the workshop) | Ask for the written diagnosis (which items are defective and why). You can get a second quote by phone — describe the fault, give the make/model/year/km, and ask for a ballpark. If significantly lower, ask the first shop to match. |
| Diagnosis fee | Most shops charge a diagnosis fee ($80–$150) that is credited against the repair if you proceed. If you take the car elsewhere, you forfeit the diagnosis fee. This is legitimate — factor it in when deciding whether to proceed or seek a second quote. |

Negotiation
What you can legitimately ask for — and how to ask
Questioning a parts price
"I looked up the part number you mentioned and found it retailing for $X at [supplier]. I understand you have a margin on parts — would you be able to get closer to $Y? Or I'm happy to supply the part myself if that works for you."
Questioning labour hours
"I've seen this job quoted at around [X] hours elsewhere. Is there something specific about my car that makes it longer? Happy to understand the difference."
| Ask | When it's reasonable |
|---|---|
| Supply your own parts | Many independent mechanics will fit customer-supplied parts (though they may not warranty the part itself). Buying an OEM part online and supplying it can reduce cost — confirm this arrangement before ordering. |
| Defer non-urgent items | If the quote includes "while we're in there" advisory items, ask which are safety-critical now vs can wait until next service. A good mechanic will give you an honest answer. |
| Loyalty/volume discount | If you've been a regular customer or are bringing in multiple jobs, ask directly. Many small workshops will offer a discount to retain a reliable customer. |
