What Should I Check Before Buying a Used Car in Australia?
Buying a used car in Australia involves more than a test drive and a mechanic's report. The checks that protect your money happen before you even inspect the vehicle — and they take less than five minutes. Here's the complete pre-purchase checklist, in the right order.
Step 1: Verify the Vehicle Identity (VIN Check)
Before anything else, confirm that the car is what the seller says it is. Ask the seller for the VIN (Vehicle Identification Number) — a 17-character code found on the dashboard (visible through the windshield), the driver's door jamb, or the registration papers.
Check that the VIN on the car physically matches what's on the registration papers and what the seller provides. If they differ, walk away immediately — this is a red flag for VIN cloning or re-plating, both of which are associated with stolen and written-off vehicle fraud.
A vehicle history report confirms identity automatically. Enter the rego plate or VIN at National VIN Check and the system verifies the make, model, year, colour, and compliance details against national records.
Step 2: PPSR Finance Check — Does Anyone Else Own This Car?
This is the most important financial check before any private sale.
The Personal Property Securities Register (PPSR) is the national database of security interests registered against vehicles. If the seller has a car loan, chattel mortgage, or finance lease, it will be registered here. Under Australian law, that debt follows the vehicle — not the seller. If you buy a car with outstanding finance, the lender can legally repossess it from you, even if you paid the seller in full and in good faith.
A PPSR check costs $2 through the government's ppsr.gov.au, or is included in all National VIN Check report tiers from $9.95 (which also adds identity verification and stolen status).
Never skip the PPSR check. It is the cheapest insurance you can buy.
Step 3: Stolen Vehicle Status
A car can be on the national stolen vehicle register and still show as PPSR-clear. The PPSR and police stolen databases are completely separate systems.
Buying a stolen vehicle — even unknowingly — can result in immediate confiscation by police. You lose the car with no compensation from the seller, and recovery of your money is typically very difficult.
A National VIN Check report cross-references national police databases in all states as part of every paid report. This is included in the Basic, Premium, and Gold tiers.
Step 4: WOVR Written-Off History
The Written-Off Vehicle Register (WOVR) records every vehicle declared a total loss by an insurer. This includes:
A repairable write-off is not necessarily unsaleable — but you must know about it before you buy, because it significantly affects the vehicle's value, insurability, and resale potential. A vehicle with undisclosed WOVR history sold at market price is misrepresented.
WOVR history is included in the Premium ($19.95) and Gold ($29.95) reports from National VIN Check.
Step 5: Registration Status
Confirm the registration is current and that the rego expiry date matches what the seller claims. An expired registration means the car cannot legally be driven on the road, and you will need to re-register it before use.
Also check that the registration is in the seller's name — if it's registered to a third party, ask why. This can be legitimate (e.g., a business vehicle) or a warning sign.
Live registration status is included in the Premium and Gold report tiers.
Step 6: Physical Inspection by a Licensed Mechanic
A vehicle history report covers your financial and legal exposure. A physical inspection by a licensed mechanic covers the mechanical condition.
Book a pre-purchase inspection (PPI) with an independent mechanic — not one recommended by the seller. A PPI typically costs $150–$300 and checks:
The PPI is essential even if all history checks come back clean.
Step 7: Test Drive
Drive the car yourself — not just around the block. At minimum:
Listen for unusual noises. Trust your instincts. A car that passes all the paper checks but feels wrong mechanically is still a bad buy.
Step 8: Valuation — Are You Paying the Right Price?
Before agreeing to a price, check what the car is actually worth. Reference sites like RedBook, CarsGuide, and Carsales give you a sense of market range.
A Gold report from National VIN Check includes an independent market valuation (low, average, and high) based on the specific make, model, year, variant, and condition — giving you data to negotiate confidently rather than guessing.
Step 9: Safety Recalls
Check whether the vehicle has any unfixed government safety recalls through the Vehicle Recalls Australia website. Active recalls must be repaired by the manufacturer at no cost — but many private sellers don't disclose them, and some buyers never know until something fails.
Active recall data is included in the Gold report tier.

How Long Does It Take?
Steps 1–7 (the vehicle history report) take under 60 seconds. Enter the rego plate or VIN at National VIN Check, choose your tier, and the PDF is in your inbox before you've finished reading this page. The mechanic inspection takes a day. The test drive takes 20 minutes.
The entire process from "considering a car" to "confident to buy" takes one afternoon. The cost of not doing it can be the entire purchase price.
