Buying a Used Car in Australia: Checks, Rights and Paperwork

Buying a used car goes best in a set order. Paperwork first: a $2 PPSR search shows whether the car is recorded as free from debt, and may flag it as stolen or written off. The at-the-car checks come second, and the paid mechanical inspection last.

The other thing worth knowing up front is that your rights are not the same everywhere. The register is national, but cooling off, warranties and clear title are state law, and they change again depending on whether you buy from a dealer or from a bloke in a driveway. Queensland, New South Wales and Victoria agree on more than you would expect, and Western Australia disagrees with all three on the protection people assume is national.

Buying a used car, step by step

Work down this list rather than across it. Each step is cheap enough to do before the next one, and each one can end the process without costing you more. When you are standing at the car, our free used car buying checklist scores it on 20 inspection points and estimates what it will cost to own.

When buying a used car, the order matters because the first three cost almost nothing and rule out the cars that were never going to work. The inspection is the expensive step, and you only want to pay for it once.

Start with the $2 PPSR search

The Personal Property Securities Register is the Commonwealth register of security interests, and its quick vehicle search costs $2, which is why it comes first rather than at the end. The PPSR says a $2 search will show you if the vehicle is recorded as free from debt, and may also tell you if the car is recorded as stolen or written off.

Queensland describes the same search in slightly more detail, saying it may confirm whether the vehicle has been written off, stolen, or is subject to outstanding debt or interests such as court orders. Either way, you get the answer from your phone before you drive across town to look at it.

The debt question is the one that catches people, because it survives the sale. Queensland explains that a vehicle can get debt attached to it where a bank lent the seller money to buy it in the first place and the seller has not fully repaid that loan by the time of sale, and that the bank can then take the vehicle back if the seller cannot finish paying, even once you own it. New South Wales puts the same point more briefly: the PPSR will tell you if there is money owing on the vehicle, or if the registered owner does not own it outright.

Queensland's own phrase for the thing you are buying is clear title, meaning free from unpaid debt. Its warning is conditional, and the condition is the whole point: if you buy a vehicle without clear title and the previous owner defaults on their debt, the lender may repossess your vehicle to recover their costs.

One detail there is worth a diary note. Queensland says a printed PPSR certificate acts as proof of clear title for 24 hours, so run the search close to the day you hand over money, not a fortnight before.

Check the car is the car

Once you are standing in front of it, the next check costs nothing and takes two minutes. Queensland tells buyers to confirm that the number plate, construction date, vehicle identification number and engine number on the registration certificate all match the vehicle exactly, and to match those against the vehicle's VIN plate.

In a private sale, check the seller as well as the car. Queensland gives this as private-purchase advice: sight the person's licence to confirm they are the registered operator, and note that the current registration certificate or vehicle registration notice is what shows who the registered operator is. Buying from a licensed dealer, the equivalent protection is the clear title guarantee rather than something you verify yourself.

If any of those four identifiers disagree with the paperwork, stop there. You are no longer looking at a bargain, you are looking at a car whose history you cannot establish.

Then check the plates for dates, because the two dates fitted to a vehicle mean different things and an advertisement will not always separate them. Queensland tells buyers to check the build and compliance dates on the plates fitted to the vehicle: the build date is the year the vehicle was manufactured, and it should match the advertised year model, while the compliance date is when the vehicle met the Australian safety standards and became legal to drive in Australia.

None of that tells you whether the engine is sound, which is the paid step. Queensland's advice, depending on the age and cost of the vehicle, is to have an independent qualified mechanic look over the vehicle, ask the previous owner for servicing records, and make sure any modifications meet legal standards and are properly approved by the Department of Transport and Main Roads.

Between the cheap paperwork and the paid mechanic there is a middle step, and Queensland's Office of Fair Trading has already written the list. It publishes this as an ownership checklist rather than as pre-purchase advice, so treat it as a guide to what to put your eyes on rather than as the state's buying instructions: all exterior lights working, the windscreen and windows free of chips, cracks or scratches, the wipers and washers working properly, the horn working, the handbrake holding the vehicle still on steep hills, seat belts in good condition, tyres in good condition and at good pressure, gauges and warning lights working, and suitable fluid and oil levels for the engine, automatic transmission, radiator, power steering, brake, clutch, battery and windscreen washers.

Nine things, and not one of them needs the car up on a hoist. A car that fails several of them in the driveway has told you something useful before you have spent a dollar on an inspection.

Written off, repairable, or neither

A write-off is not automatically a deal breaker, but it is a fork in the road, and the two kinds are very different animals. In Queensland a repairable write-off must pass a written-off inspection before it can be registered, while a statutory write-off can never be registered at all.

That distinction is worth checking before you fall in love with the price, and at auction the timing is in your favour. Queensland requires a chattel auctioneer to announce before an auction whether a vehicle is a repairable write-off or a statutory write-off, whether it has sustained water damage, and whether it does or does not have a statutory warranty, so the disclosure arrives while you can still walk away. What you usually cannot do there is drive it: Queensland says you are generally not allowed to test drive a vehicle before bidding, though you should be able to inspect it.

There is an age limit on the paper trail. Queensland lists vehicles under 15 years old that have been written off on its written-off register, so an older car can have a history the register does not carry, which is another argument for the mechanical inspection further down this list.

Dealer or private: what you are actually buying

The price difference between a dealer car and a private one is not just margin. It is a bundle of rights, and Queensland sets out both sides of that bundle in writing.

That is Queensland's list, and other states set their own. The point is not the specific entitlements but the shape of the trade: a private sale can be cheaper because you are carrying the risk the dealer would otherwise carry, so the checks in this guide matter more, not less, when you buy privately.

Queensland spells out what a private buyer has to establish alone: that the vehicle belongs to the person selling it and is not listed as stolen, that it is what the person says it is, that it has no unpaid debt attached, and that it is going to keep you safe.

The statutory warranty test people get wrong

Buyers often assume a used car from a dealer comes with a warranty. In Queensland, New South Wales and Victoria that is broadly right, and the genuine surprise is that all three run the same basic test. Cross either of its two thresholds, though, and Queensland and New South Wales go opposite ways.

The test is the car's age and its odometer. Under 10 years old and under 160,000 km, bought from a licensed dealer, and you get 3 months or 5,000 km of cover, whichever comes first. All three governments publish those numbers independently of each other, and Consumer Affairs Victoria adds, for Victoria, that the car's age is determined by the date stamped on its build plate.

Cross a threshold and the consequence is a border, not a sliding scale. An 11-year-old car bought from a Queensland dealer still carries a class B warranty of one month or 1,000 km. The identical car bought in New South Wales carries nothing under the dealer guarantee, because NSW lists a used car over 10 years old as an exclusion from it.

Western Australia sets its own numbers and applies a purchase price floor, so an eastern-states rule of thumb does not survive the trip across the Nullarbor. WA publishes its entitlements as an age column and a distance column, and does not state on that page whether the two are read together or separately, so treat a car near either boundary as a question for Consumer Protection rather than a calculation you can do yourself.

Note where the first boundary sits, because it is easy to read past. A car at exactly 10 years is in the top tier on Western Australia's wording, not the middle one, because the middle tier begins at more than 10 years. The distance columns meet at 150,000 km rather than dividing cleanly, which is a second reason to ask rather than assume.

Western Australia also puts a specific duty on the dealer. The dealer must give you an information statement about the statutory warranty, if any, that applies, and that statement sets out what is and is not covered. If you are buying in WA and no statement appears, that is a question worth asking before you sign.

Names matter here too. New South Wales calls it a dealer guarantee rather than a statutory warranty, so a buyer searching the Queensland or Victorian term will not find it on the NSW page and may conclude there is nothing there.

Two more edges are worth knowing before you lean on any of this. Consumer Affairs Victoria states, for Victoria, that if you sell the car privately before the 3 months or 5,000 km are up, the statutory warranty does not transfer to the new owner, and the Queensland and NSW pages checked here do not address transfer either way. In Queensland, a vehicle 20 years old or more offered at auction for restoration is treated as restorable: no statutory warranty at all, with consumer guarantees what is left.

Consumer guarantees sit underneath all of that and work differently again. Queensland describes the reasonable time for a guarantee as something that varies from vehicle to vehicle, depends on the price and quality of the specific vehicle, and is not defined by when other warranties run out.

Queensland also publishes what a statutory warranty does not reach, which is worth reading before you rely on one. Its list of parts a statutory warranty does not cover includes tyres and tyre tubes, batteries, fitted airbags, radiator hoses, most lights, an installed radio or CD player, and consumables such as spark plugs, wiper rubbers and oil filters.

Cooling off is shorter, and easier to lose, than you think

This is the step where a good checklist earns its keep, because cooling off is the protection people assume is national and it is nothing of the sort. Four states, four different answers, and in one of them there is no cooling-off period at all.

Read the New South Wales column twice. Cooling off there is written around the finance rather than the car: New South Wales states that the period applies where the dealership arranges your loan or refers you to a credit provider, and makes the notice part of the contract as a Form 12 in those cases. It does not state a cooling-off period for dealer sales without a linked credit arrangement, so if you are buying in New South Wales without dealer finance, ask NSW Fair Trading what applies to you rather than assuming either way.

Where a cooling-off period does exist, the common thread is how easily it ends. Queensland says taking the vehicle home ends the period straight away and you give up your right to it; Victoria says accepting delivery during the three days loses it automatically. In both states the fix is the same: leave the car where it is until you have made up your mind.

What you can do without losing the period depends on which state you are in, and this is where a national rule of thumb gets expensive. Queensland confirms you keep the cooling-off period if you take the vehicle to an independent mechanic for an inspection or for a test drive, so on a Queensland dealer purchase that window is exactly when the inspection belongs.

Victoria says nothing of the kind. Its page states only that accepting delivery during the three days loses the period automatically, and nothing registered here establishes that a trip to a mechanic is not delivery, so in Victoria get the inspection done before you sign rather than during the three days. On a private sale in Queensland there is no cooling-off window at all, so the same rule applies there.

Both Victoria and Queensland require written notice if you change your mind. Put it in writing rather than ringing.

Certificates, and what they do not tell you

A current safety certificate is not evidence that a car is mechanically sound, and treating it as one is a common and expensive mistake. Queensland states plainly that a safety certificate inspection is not a comprehensive mechanical inspection on the quality, or life expectancy of a vehicle, and recommends a motoring group such as RACQ for a full mechanical inspection.

Check the certificate is still current as well as present. In Queensland a certificate for a private sale lapses at 2,000 km or 2 months, whichever comes first, and at 1,000 km or 3 months for a motor dealer purchase. Handwritten certificates must be displayed on the vehicle, and where one has been issued electronically the seller must produce it on request instead.

One extra document catches LPG buyers out. Queensland asks buyers to check that a gas certificate, where one is needed, is within 3 months from its date of issue for a private or a dealer sale alike.

After you shake hands

Registration is the loose end that costs money if you leave it. Queensland requires a vehicle bought while registered in another state or territory to be registered in Queensland if you plan to garage it there, so an interstate bargain carries an administrative tail worth pricing in before you buy.

How you arrange the money is your call, but in New South Wales it decides whether the stated cooling-off period applies, so it is not a decision you can make separately. NSW states that its cooling-off period applies where the dealership arranges your loan or refers you to a credit provider.

Read that in both directions before you choose. Finance the dealer arranges or refers you to is what creates that cooling-off period in New South Wales, and arranging your own finance means the NSW page does not state one for your purchase. Our car loans page sets out how the repayments work if you go that way, and the car loan calculator shows the weekly, fortnightly and monthly repayment for a given amount, rate and term.

Then keep the paperwork. The PPSR result, the safety certificate, the inspection report and the logbook are what prove the car's history to the next buyer, and filing them takes about two minutes on the day you buy.
