South Australia Used Car Dispute — Private Sale and Dealer Claims in Court

Private Sale and Dealer: Two Different Legal Paths

A used car that breaks down weeks after purchase is the same problem for the buyer either way. But the law treats private sales and dealer sales differently — and the form you use to file your claim changes too.

If you bought from a licensed dealer, Australian Consumer Law consumer guarantees apply. The car must be of acceptable quality, fit for purpose, and match the description. Dealer disputes can use the specialised Form 1C under the Second-hand Vehicle Dealers Act 1995, or the standard Form 1 under ACL.

If you bought from a private seller, consumer guarantees do not apply — those only cover goods sold "in trade or commerce." Your claim is for breach of contract or misleading conduct under the general law.

Both go to the Minor Civil Claims Division of the SA Magistrates Court if the claim is A$12,000 or less.

Dealer Claims: What You Can Argue

When a dealer sells you a car with an undisclosed defect, you have several grounds:

Major failure under ACL — the car is unsafe, substantially unfit for purpose, or would not have been bought if the defect had been known. A major failure entitles you to reject the car and demand a full refund, not just a repair.

Minor failure — the dealer can choose to repair the defect within a reasonable time. If the dealer does not do so, you can have it repaired elsewhere and recover reasonable repair costs; you may reject the car if the ACL rejection requirements are met.

Misrepresentation — the dealer described the car as "mechanically sound" or "no accidents" when the opposite was true. This is actionable under the Australian Consumer Law prohibitions on misleading conduct.

Statutory warranty — under the Second-hand Vehicle Dealers Act 1995, certain used vehicles sold by licensed dealers carry a statutory warranty. Check whether your car qualifies based on its age, mileage, and price.

Private Sale Claims: What You Can Argue

Without ACL consumer guarantees, your private sale claim relies on:

Breach of contract — the seller promised something specific (in writing, by text, or in the online listing) and the car did not match. "Low kilometres, never been in an accident" followed by a mechanic finding collision damage gives you a breach claim.

Misrepresentation or deceit — the ACL misleading-conduct ban applies to conduct in trade or commerce, so a private-sale claim for a false statement relies on common law, including misrepresentation or deceit.

If the seller knowingly or recklessly made a false statement — for example, that the odometer had not been rolled back or the car had never been written off — intending you to rely on it, and you relied on it and suffered loss, that may support a common-law deceit claim.

Evidence That Matters

Used car disputes are won or lost on documentation:

• The original listing (screenshot it before the seller takes it down — Gumtree, Facebook Marketplace, or Carsales)
• The contract of sale or receipt
• Pre-purchase inspection report (if you had one done)
• A post-purchase mechanic's report identifying the defect and estimating repair cost
• Two independent repair quotes to establish the reasonable cost
• Any text messages or emails where the seller made claims about the car's condition
• PPSR (Personal Property Securities Register) search showing whether the car has finance owing, has been written off, or has been stolen

What You Can Claim

For a major failure with a dealer, you can claim a full refund of the purchase price. For a minor failure or private sale misrepresentation, you typically claim the cost of repair or the diminution in value — the difference between what you paid and what the car is actually worth given its true condition.

If the repair cost exceeds A$12,000, the claim exceeds the minor civil limit. You can either cap your claim at A$12,000 (formally abandoning the excess on your statement of claim) or file in the General Claims Division.

Filing Your Claim

Send a letter of demand or Form P1 Final Notice to the seller with a 21-day deadline. If they do not pay or negotiate, file on CourtSA using Form 1 (private sale) or Form 1C (dealer under the Second-hand Vehicle Dealers Act). The filing fee is A$186.
