Buying a used car in Australia means weighing a lower price against higher risk. Before you buy, run a PPSR search to confirm the vehicle isn’t stolen, written off or under finance, arrange a pre-purchase inspection, and check what warranty (if any) applies. This guide covers where to buy, finance, warranties, government charges and the checks that protect you.

A used car is any previously registered vehicle being resold by a private individual or licensed dealer. In 2025, Australians bought 2,324,805 used cars – nearly twice the number of new cars sold. Used cars cost less to buy, but carry greater risk: condition, reliability and remaining lifespan depend entirely on prior maintenance and ownership history.
Used cars are available through licensed dealers, private sellers, and online platforms including carsales, CarsGuide, Facebook Marketplace and Gumtree. Each channel carries different levels of buyer protection.
Dealer purchases offer statutory warranty coverage and greater recourse under Australian Consumer Law. Private sales are buyer beware – no warranty applies and legal recourse is limited unless the seller misrepresented the vehicle.

Most buyers start online, comparing prices across dealer and private listings before inspecting in person. Never rely on photos or videos alone – always inspect physically and bring someone familiar with vehicles.
Two checks are essential before any purchase:
Finance Type | How It Works | Key Consideration |
Secured car loan | Most common; vehicle used as security | Lower rates, but repossession risk on default |
Dealer finance | Arranged at point of sale | Convenient, but not always the cheapest option |
Novated lease | Employer pays from pre-tax salary | Reduces taxable income; can include running costs |
Unsecured personal loan | Based on credit profile, not vehicle value | Suits older vehicles or private purchases |

Most licensed dealers must provide a statutory warranty by law. The national baseline is 3 months or 5000km, but state rules vary:
Private sales carry no statutory warranty. Government charges typically add $1500–$2500 or more to the purchase price, covering stamp duty (ACT exempts electric vehicles (EVs) and hydrogen vehicles), registration transfer, and compulsory third-party insurance (a separate Green Slip applies in NSW and ACT).
Is it safer to buy from a dealer or privately?
Dealer purchases offer more legal protection: statutory warranty, roadworthy certificate and greater recourse under Australian Consumer Law. Private sales are buyer beware – less recourse exists unless the vehicle was misrepresented.
Must the vehicle come with a roadworthy certificate?
A roadworthy certificate is legally required when a used vehicle is re-registered with a change of ownership in Victoria and Queensland. Rules and vehicle safety inspections vary in other states.
Can I claim a used car purchase on tax?
Yes, if used for work or business purposes – running costs may be claimable. No deduction applies to purely personal use.
What is a novated lease on a used car?
A novated lease is a salary packaging arrangement where your employer pays the lease from your pre-tax income, reducing your taxable income. It is available on used vehicles and can include fuel, servicing, registration and insurance.

A vehicle purchased while still under finance can be legally repossessed by the original lender – leaving the buyer without the car and out of pocket. A written-off vehicle may be unsafe, unroadworthy or uninsurable.
Scammers are increasingly active on Facebook Marketplace and Gumtree, using fake listings, cloned vehicles and fraudulent identities. Always verify the seller’s identity, run a PPSR search, and arrange a motoring club inspection if in any doubt. Buyers who unknowingly purchase from an unlicensed dealer posing as a private seller may still have recourse under Australian Consumer Law.
Disclaimer: Rules and charges vary between states and territories and are subject to change. Always check with your local transport or consumer affairs authority for the most current information.
