Buying a used car is not just about finding the right make, model and price. You are also deciding whether the particular vehicle in front of you is worth the money being asked for it. This guide walks you through the process from the first search to the final payment, with a focus on the checks that can reduce avoidable surprises.
1. Start with a realistic budget
Set the purchase budget first, then leave room for registration, insurance, servicing, tyres, repairs and other ownership costs. The cheapest car to buy is not always the cheapest car to own.
For older or higher kilometre vehicles, keep a repair buffer. For EVs, consider charging access and the condition of the battery as part of the overall purchase decision.
2. Choose the right vehicle for your use
Think about how the car will actually be used: commuting, family trips, towing, long-distance driving, rideshare, city driving or occasional weekend use.
For an EV, consider charging access and expected range. For a hybrid, consider both the combustion and high voltage systems. For a 4WD or UTE, consider towing, modifications and underbody use.
3. Research the model – then the individual car
Model research is useful for understanding common maintenance needs, specifications and ownership considerations. But a good reputation for a model does not guarantee that an individual used example is in good condition.
The vehicle’s age, mileage, service history, accident history, previous use and maintenance matter.
4. Verify the vehicle identity
Before paying a deposit, make sure the VIN or chassis number, registration details and vehicle details are consistent. If something does not match, stop and clarify it.
5. Run a PPSR search
A current PPSR search can tell you whether a security interest is recorded and may provide stolen or written-off information where available. It does not replace a mechanical inspection.
For private purchases, the PPSR is particularly important because the register can affect the risk associated with a vehicle carrying a security interest.
6. Review service history
Look for evidence of servicing, major maintenance and previous repairs. Check whether the recorded mileage makes sense across the documents.
If the seller says a major component has recently been replaced, ask what was replaced, when, and whether supporting documentation is available.
7. Inspect the vehicle before you commit
Look at the body, paint, tyres, wheels, glass, lights, interior, engine bay and visible mechanical components. Then assess the vehicle on the road.
Do not rely only on a seller’s statement that a mechanic has looked at it. Ask what was checked and whether you can review the report.
For higher value or complex vehicles, an independent pre-purchase inspection gives you a buyer-focused assessment rather than relying only on the seller’s description.
8. Test drive properly
Check starting, acceleration, braking, steering, transmission, suspension, noise and temperature. Where appropriate, drive at different speeds and over different road surfaces.
If you are unfamiliar with the vehicle, ask an experienced person or independent inspector to assess the driving behaviour.
9. Understand the role of an RWC
In Victoria, a roadworthy certificate is intended to show that the vehicle is safe enough to be used on public roads. It is not a full mechanical-quality or reliability report.
If an RWC is required for your transaction, use an accredited/licensed tester and treat the certificate as a separate requirement from a buyer-focused condition inspection.
10. For EVs, investigate the battery
The battery is a central part of a used EV’s value and usability. Government guidance notes that battery State of Health (SOH) information can help when buying or selling a second hand EV.
A battery health assessment can provide information that a dashboard range estimate alone cannot. If battery condition is important to the purchase, consider an independent battery test.
11. Negotiate using evidence
Do not negotiate simply because ‘used cars always have problems.’ Use actual findings, tyres, brakes, suspension, leaks, damage, service requirements, battery condition and other documented issues.
The stronger your evidence, the easier it is to have a sensible conversation about price.
12. Do the final checks before payment
Reconfirm the vehicle identity, PPSR result, agreed price, inclusions, service documents, keys, accessories and payment arrangements.
If something material changes between inspection and handover, stop and investigate it.
13. Keep your records
Save the PPSR certificate, inspection report, service documents, receipts, sale contract and any written promises made by the seller.
These records can be useful later for servicing, resale and resolving questions about what was represented at the time of purchase.
