Buying a used car

A pre-purchase inspection is an independent advisory report on a used vehicle's actual condition, engine, transmission, accident history indicators, electronic fault codes. A roadworthy is a regulatory pass/fail document that confirms the car meets the legal minimum for transfer of registration. They are different inspections; serious buyers get both. Mobile operators come to the seller's driveway, do the inspection in 60–90 minutes, and email a written report.

Frequently asked questions

Do I really need a pre-purchase inspection?
On a $25,000 used car purchase, $300 spent on a thorough pre-purchase inspection is the cheapest insurance available. It catches accident history, drivetrain wear, and fault codes that a roadworthy never tests for.
What is the difference between a pre-purchase inspection and a roadworthy?
A roadworthy is pass/fail against a regulator standard, it proves the car meets the legal minimum. A pre-purchase inspection is a graded report on the actual condition of the vehicle: engine compression, transmission feel, accident history indicators, electronic fault codes.
Can the same inspector do both?
Often yes, especially mobile operators who service used-car buyers. Confirm the operator holds the inspection licence to issue a roadworthy in your state and ask for a written pre-purchase report alongside.
How much does a pre-purchase inspection cost?
Typically $200–$400. The variance is driven by how thorough the report is and whether a road test and electronic scan are included. Combined with a roadworthy, expect $50–$100 saved over booking separately.
How long does it take?
Allow 60–90 minutes for a thorough pre-purchase report including road test and electronic scan. Add 30 minutes if a roadworthy is being done in the same visit.
Should the seller be present?
It is fine if they are, and many private sellers will be. The inspector reports to whoever booked them, that is the buyer. The seller does not see the report unless the buyer chooses to share.
Will a pre-purchase inspection check the title and finance?
No. The inspection covers physical condition. To check for finance owing or write-off history, run a separate PPSR (Personal Property Securities Register) search, it costs about $2 and takes minutes online.
