Buying from a licensed dealer costs more than buying privately for a reason you should actually use: in most of Australia a used car under a certain age and distance comes with a statutory warranty by law, and several states give you days to change your mind after signing. Private sales offer neither. Knowing exactly where the floor sits turns the dealer premium from a cost into a choice.
The Australian Consumer Law applies to every dealer sale everywhere in Australia. The statutory warranty and cooling-off layers on top of it are state law — and they differ more than most buyers expect.
The national floor: Australian Consumer Law
Whatever the state, a dealer sale carries consumer guarantees: the car must be of acceptable quality, match its description, be fit for disclosed purpose, and come with clear title. These cannot be excluded, and they apply regardless of age or kilometres — an old car must still be as described and roadworthy-usable. Everything below is extra protection on top.
Statutory warranty: the 10-years / 160,000 km pattern
Most states converge on the same trigger. Queensland's scheme is typical: a class A statutory warranty applies when the car has travelled less than 160,000 km and its build date is within the last ten years, lasting 3 months or the first 5,000 km; older or longer-travelled cars get a reduced class B warranty of 1 month / 1,000 km, sold by licensed dealers and chattel auctioneers alike.(Queensland Government) Victoria matches it: Consumer Affairs Victoria requires licensed motor car traders to give 3 months / 5,000 km on cars less than 10 years old with under 160,000 km — excluding commercial vehicles and motorcycles.(Consumer Affairs Victoria)
New South Wales reaches a similar result through "dealer guarantees" under its Motor Dealers and Repairers Act: used cars under 10 years old and 160,000 km carry a 3 months / 5,000 km guarantee, with separate tables for new vehicles (12 months / 20,000 km) and motorcycles.(NSW Government)
Two things people miss:
- Existing defects can be excluded. Dealers list known faults on a notice (Victoria's Existing Defects Notice, NSW's Form 5/7) and those listed items are not covered. Read it before you sign; a vague laundry list is a reason to walk.
- The warranty doesn't survive a quick resale. Victoria's scheme attaches to the buyer personally — sell the car privately two months in and the remainder doesn't transfer.
Not every state legislates a fixed statutory-warranty table the way the eastern states do — in some jurisdictions your protection is purely the ACL guarantees plus whatever written warranty the dealer offers. Check your own regulator before assuming the 3-month floor exists where you live.
Cooling-off: the state lottery
This one varies sharply, and mostly only bites at licensed dealers:
- Queensland — 1 business day on licensed-dealer used car contracts, ending 5pm the dealer's next business day. Drive the car away during the window and you forfeit it. The penalty for cancelling is capped ($100); no form handed over means the window extends to seven days.(qld.gov.au)
- South Australia — 2 clear business days on second-hand cars from dealers (demos included), with the dealer keeping at most 2% of the contract price or $100, whichever is less. Auctions, new cars and private sales are excluded.(sa.gov.au)
- ACT — 3 clear business days under the Sale of Motor Vehicles Act, waivable by signing the approved form before delivery, with cancellation costs around $100 or 1% of price whichever is greater.(AustLII, SOMVA s25B)
- New South Wales — the general used-car contract binds you on signature; the cooling-off right exists for linked credit arrangements (the dealer arranged or referred your finance), giving 1 business day to cancel for the lesser of $250 or 2% of price.(nsw.gov.au)
- Victoria — a cooling-off right exists for licensed-trader used car sales; confirm the current window and waiver rules with Consumer Affairs Victoria before relying on it.
- WA, Tasmania, NT — no general used-car cooling-off entitlement we could verify; treat the signature as binding and confirm with your local regulator.
Where none of this follows you
Private sales have no statutory warranty, no cooling-off and no dealer guarantee anywhere in Australia — the ACL's misleading-conduct rules are essentially all that's left, which is why our guides lean so hard on inspection and PPSR checks before money moves. Auctions sit nearly as bare, as their own guide explains.
How to use this at the dealership
Ask three questions before signing: what statutory warranty or dealer guarantee applies to this specific car (age/km decides), what's on the defects notice, and whether any finance being arranged changes my cancellation rights. Get the answers on the forms, not in conversation. And if the deal feels rushed past your state's window — that urgency is precisely what the legislation was written to interrupt.
What this means if you're selling on MotorLoop
None of these protections apply when you sell privately, and buyers know it — which is why private sellers who offer a PPSR certificate, an inspection report and honest photos close the trust gap that dealers charge to bridge. Listing is free, and the paperwork habits that protect buyers make yours the listing they answer.
