Buying a second-hand car in Australia can save you serious money, but only if you go in with a plan. Used car prices have softened since their 2023 peak, so there are good deals out there. There are also plenty of cars hiding problems the seller hopes you won't spot.
These 10 tips will help you buy with confidence, whether at a dealership, privately, or at auction.
Work out what you can spend before you start looking. The sticker price is only part of it. Factor in stamp duty, registration transfer, insurance, and a buffer for repairs. If you're using finance, get pre-approved on a car loan first. Keep total ownership costs under 15% of your take-home pay. If you've got a car to trade in, get a valuation first so you know what you're working with.
It's easy to fall in love with a car that doesn't suit your life. School runs and city driving point to something small and economical. Towing a boat points elsewhere. Once you've shortlisted two or three models, read up on common faults, parts availability, and service costs. Some brands are expensive to maintain.
Spend an hour on Carsales, Drive, and Facebook Marketplace looking at the same model, year, and kilometres you're considering. You'll get a feel for what's fair and what's overcooked, so you'll know straight away if there's room to move.
Each option has trade-offs. Licensed dealers cost more but offer statutory warranties on cars under 10 years old or 160,000 km. Private sellers are cheaper, but you're buying as-is with no warranty. Auctions can produce bargains, but you often can't test drive, and you're committed once the hammer drops. First-time buyers are usually better off at a reputable dealer.
A good seller answers questions directly, has the paperwork ready, and lets you take the car to a mechanic. Walk away from anyone who pressures you on the spot, refuses an inspection, or wants cash with no receipt. For dealers, check Google reviews. For private sales, the seller's name must match the registration papers. Mismatches are a red flag for stolen vehicles or unpaid finance.
A Personal Property Securities Register check costs about $2 and takes minutes. It tells you whether the car has money owing on it, has been written off, or was reported stolen. Skip this, and if the previous owner had a finance attached, the lender can repossess the car from you, even after you've paid in full. Use the VIN, not the number plate.
The Vehicle Identification Number is a 17-character code stamped on the car (usually at the base of the windscreen). It must match the registration papers exactly. Then ask for the logbook. Regular stamps every 10,000 to 15,000 km show the previous owner cared. Big gaps suggest neglect.
Five minutes around the block isn't enough. Drive the car cold, ideally first thing in the morning, so you can hear how it starts. Take it on a mix of city streets and highways. Listen for knocks, rattles, or whining. Check the brakes pull up straight, the steering doesn't pull to one side, and the gearbox shifts smoothly. Turn the radio off.
Spending $200 to $300 on an independent mechanical inspection is the best money you'll spend. A qualified mechanic will catch things you can't, like worn timing belts, head gasket trouble, or signs of past collision damage. If the seller refuses, that's your answer.
Once you're happy with the car, make an offer below asking and use anything from the inspection or test drive as a reason for a lower price. Pay by bank transfer, never large amounts of cash. Get a signed receipt with the seller's full name, address, the VIN, the price, and the date. Then transfer the registration into your name within the timeframe your state requires (14 days in Queensland) so you're covered legally and for insurance.
Take your time. Rushing is how people end up with someone else's problems. Work through these 10 tips, and you'll drive away with a car you can count on.

Q1. What are the most important checks to conduct before buying a used car?
Start with the paperwork. A PPSR check tells you whether the car has finance owing, has been written off, or was reported stolen. The VIN on the car must match the registration papers exactly, and the seller's name on the rego should match their ID. Then look at the service history for regular logbook stamps. Once the paperwork stacks up, move to the car itself. Check the engine bay for oil leaks, cracked hoses, or coolant residue. Look under the car for fluid stains. Inspect the tyres for uneven wear, the body for mismatched paint or panel gaps, and the interior for water damage or excessive wear. Then take it for a proper test drive on a mix of roads. The single best check, though, is paying a qualified mechanic $200 to $300 for an independent pre-purchase inspection. They'll catch things you can't.
Q2. What documentation do I need when purchasing a second-hand vehicle?
You need the current registration papers in the seller's name, the logbook with stamped service history, and a signed receipt that includes the seller's full name, address, driver's licence number, the VIN, the price, and the date of sale. Most states also require a roadworthy or safety certificate before registration can be transferred. Queensland calls it a Safety Certificate, Victoria a Roadworthy Certificate, and NSW uses an eSafety check (pink slip) for older vehicles. You'll also want your PPSR certificate as proof that you ran the check. After the sale, you'll need to lodge a transfer of registration with your state transport authority within the required timeframe (14 days in Queensland) and arrange your own insurance before you drive the car home.
Q3. What are the risks associated with buying from private sellers?
Private sales are cheaper, but you take on more risk. The biggest one is the unpaid finance attached to the car. If the previous owner still owes money on it and you skip the PPSR check, the lender can repossess the car from you, even after you've paid in full. There's also no statutory warranty on a private sale, so if the engine fails the week after you drive away, that's your problem to fix. Private sellers can also misrepresent the car's history, hide accident damage, or wind back the odometer. You have very limited legal recourse unless you can prove the seller deliberately deceived you. None of this means you should avoid private sales, but you do need to be more careful. Always run a PPSR check, get an independent mechanical inspection, and verify the seller's ID matches the registration papers before handing over money.
Q4. How can I ensure I'm getting a fair price for a used car?
Do your homework before you walk in. Spend an hour on Carsales, Drive, and Facebook Marketplace looking at the same make, model, year, and kilometres you're considering. Five or six listings will give you a clear picture of the market range. Save the listings so you can refer back to them during negotiations. Redbook and Glass's also publish independent used car valuations that give you a reference point separate from what sellers are asking. Cars priced well below the average are either real bargains or hiding something, so check those carefully. Once you've got the car you want, use anything you found during the inspection or test drive (worn tyres, upcoming timing belt service, small dents) as a reason for a lower offer. Most sellers expect some negotiation and price their listings with a buffer.
Q5. What steps should I take if I find issues with the car after purchase?
Your options depend on where you bought it. Cars purchased from a licensed dealer are covered by the Australian Consumer Law, which says the car must be of acceptable quality and match its description. If a major fault appears within a reasonable time, you may be entitled to a repair, refund, or replacement. Most states also have statutory warranties on dealer cars under 10 years old or 160,000 km that cover major mechanical faults for a set period (typically three months or 5,000 km). Start by contacting the dealer in writing, explaining the issue, and asking how they'll resolve it. If they refuse, escalate to your state's consumer protection body (Fair Trading in NSW, Consumer Affairs Victoria, the Office of Fair Trading in Queensland). For private sales, your options are very limited. You'd need to prove the seller knowingly misrepresented the car, which usually means going through a small claims tribunal. This is why getting a pre-purchase inspection before you buy is so important. Catching issues before money changes hands is far easier than chasing them afterwards.
