A pre-purchase car inspection (PPI) is an independent mechanical inspection you commission before buying a used car. At Bosch Service Brisbane it takes around two hours in the workshop, and covers the brakes, suspension, underbody, engine, cooling system, electronics and a road test, finished with a written report and a phone call from the mechanic who inspected the car. In Queensland the seller’s safety certificate does not do this job for you, and the difference matters most on European cars, where one missed fault can cost many times the inspection fee.
Roadworthy vs pre-purchase inspection: not the same thing
| Safety certificate (RWC) | Pre-purchase inspection | |
|---|---|---|
| Who it protects | The public (minimum safety standards) | You, the buyer |
| Engine & transmission health | Not assessed | Assessed, including a road test |
| Fault codes & electronics | Not scanned | Scanned |
| Service history review | No | Yes |
| Negotiating power | None | An itemised list with repair costs |
What the inspection covers
The car goes on a hoist, something no driveway inspection can offer. We check brake pad and rotor wear, suspension components and bushes, underbody rust and accident evidence, engine and transmission leaks, cooling system condition, battery health, tyre wear patterns and every light and accessory. A diagnostic scan pulls stored fault codes, and a road test picks up what a stationary car never shows: clutch engagement, transmission shifts, steering feel and noises.
What it can save you
These are the faults a PPI is designed to catch before you hand over the money, each one a repair that routinely runs into the thousands on a European car:
- A worn clutch and dual-mass flywheel on a European manual
- Brake pads and rotors needing replacement on both axles
- A failing air conditioning compressor
- Head gasket problems on a European engine
Any one of these, found first, either comes off the price or saves you from the car entirely. That’s the whole economics of a pre-purchase inspection: it costs a small fraction of the cheapest item on that list.
Using the report
The report is an itemised negotiating document: what needs doing now, what’s coming up, and roughly what it costs. We’ve written a separate guide on how to negotiate after a pre-purchase inspection. Sellers respond very differently to an itemised list of faults from a qualified mechanic than to a vague “can you do better on price?”.
Buying this week? Book a pre-purchase inspection at any of our five Brisbane workshops. Same or next day slots are usually available, and the seller can drop the car to whichever workshop is closest.
