Selling a car with accident history: disclosure and value

Be upfront about it, even in a private sale: WA Consumer Protection warns that a private seller may be held liable for a known serious defect they don’t disclose. If you sell or trade in to a dealer, expect to be asked and checked, because the ACCC says dealers must not mislead buyers about accident history or written-off status. A repaired car can still sell for less than one with a clean history, but repair paperwork gives a buyer fewer reasons to discount than a repair they find on their own.

If your car has ever been written off, our guide to selling a repairable write-off covers the register, the re-registration rules and what buyers check.

Do you have to disclose accident history in a private sale?

The rules that protect car buyers are written mainly for dealers. The ACCC says most consumer guarantees and state and territory laws don’t apply to second-hand cars bought through private or auction sales. WA Consumer Protection puts it more bluntly: the Australian Consumer Law doesn’t apply to cars bought and sold privately.

That isn’t a licence to hide things. On the same page, WA Consumer Protection warns private sellers that they may be held liable if they know about a serious defect and don’t tell the buyer. Wherever you live, treat that warning as the safe standard.

In practice, that comes down to three rules:

• Never say “no accidents” when there’s been one. A false answer to a direct question is the line you don’t cross.
• Disclose anything serious you know about, especially structural damage or a repair that affects safety.
• Put it in writing. A message or a line on the receipt shows what the buyer knew before they paid.

What happens if a buyer finds out after the sale? Because consumer law mostly doesn’t cover private sales, there may be no agency to step in. In NSW, for example, the NSW Government says NSW Fair Trading is unable to help resolve issues with private sales, so a dispute is usually between you and the buyer. Our guide to what to do when a private buyer wants a refund covers how those disputes play out. Telling the buyer up front is the simplest way to avoid one.

What does a dealer have to disclose when it resells your car?

The rules are different for dealers. The ACCC says a dealer must not mislead buyers about a car’s kilometres, service history, accident history or written-off status. Second-hand cars bought from a licensed dealer also come with consumer guarantees that private sales mostly don’t.

NSW goes further. The NSW Government’s guidance on where to buy a vehicle says a motor dealer must disclose any information that might affect a buyer’s decision to buy a car, or to buy it at a certain price. That information goes in the dealer notice attached to the car, and the list includes major modifications, past flood, hail or water damage, and whether the car has been written off.

This matters to you as a seller for two reasons:

• The dealer will ask, and check. A dealer can’t meet its duty to the next buyer without knowing the history. Expect questions on the valuation call and a careful look at the inspection. The same applies when a dealer appraises your trade-in.
• The history follows the car. If a dealer has to disclose past hail damage or a write-off when it resells, the next buyer sees it. That shapes what the dealer can offer you.

Broadly, when you sell to a licensed dealer, the duties to the next buyer sit with the dealer, not you. Your part is to describe the car accurately.

Why can a repaired car be worth less than an identical one?

A repair can be perfect and still cost you money, because buyers pay for certainty. Two cars with the same model, year and kilometres look identical on paper. If one has a repair history, the buyer has questions the other car doesn’t raise: was everything behind the panel checked, does the paint match in every light, will the next buyer ask the same questions?

Some buyers won’t consider a repaired car at all, and some instant online offer services won’t take a car with a major accident or a write-off in its history. Fewer people competing for the car means less pressure on the price.

That gap is often called diminished value. There’s no standard figure for it. You’ll see rough percentages quoted on forums, but they’re opinions, not data, and the real effect depends on what was damaged, how well it was repaired and what paperwork you have.

On many late-model cars, the cameras and radar sensors for driver-assistance features sit behind the windscreen, grille or bumper. If the repair touched those areas, a buyer may ask whether the sensors were checked or recalibrated afterwards.

This decision guide shows what a buyer worries about for each kind of history, and what helps answer it:

If the damage hasn’t been repaired yet, whether to fix it, claim it or sell as-is is its own decision. Our guide to hail damage: claim, repair or sell walks through it, and most of the same thinking applies to other damage.

Is a repaired accident the same as a write-off?

No. Many accidents end with an insurance claim, a repair and the car back on the road. That doesn’t put the car on a written-off vehicle register.

A write-off is different. When a damaged car is assessed as a total loss, it’s generally recorded on a written-off vehicle register as one of two kinds:

• A statutory write-off can never be re-registered or driven on the road again.
• A repairable write-off may be repaired and re-registered, depending on the state’s rules.

Those rules differ between states, and NSW sets tight limits. Transport for NSW says it will consider repair and re-registration of a written-off light vehicle only in very limited circumstances. The car must not have damage that meets the statutory write-off criteria. The applicant must also be the same registered operator with a car that only has hail damage, or have been the registered operator for more than 28 days before the damage, or have inherited the car from the registered operator.

Repairs can’t start until Transport for NSW has authorised them, and the repaired car goes through two inspections before it can be registered. If it is re-registered, the write-off is noted on the certificate of registration.

You’ll also see rules of thumb on forums for how much a write-off history takes off the price. Like the diminished value percentages, they’re opinions, not data.

So a repaired accident is something you explain. A write-off is something the buyer can usually look up.

Will a buyer find out about the accident anyway?

A write-off can show up in a search. A repaired accident usually shows up on the car itself, if the buyer looks closely. Here is what a careful buyer or dealer checks, and what each check can reveal:

• A PPSR search. A PPSR search on the VIN costs $2 online as at October 2026. It shows whether a security interest (money owing) is recorded against the car and, where the data is available, written-off and stolen status. It doesn’t show accident or repair history, so a repaired accident that never led to a write-off won’t appear. Our guide to finance showing on the PPSR explains the money-owing side of the certificate.
• State records. In NSW, a re-registered write-off is noted on the certificate of registration. In Tasmania, Rego Check can show whether a car is listed as written off.
• The paint and panels. Inspectors look along each panel for colour differences, overspray, ripples and uneven gaps, and some use a paint thickness gauge, which can point to panels that have been refinished.
• Hidden areas. Fresh paint or disturbed bolts under the bonnet, in the boot or along the door frames can suggest parts have been replaced.
• The dashboard. An airbag (SRS) warning light that stays on, or a scan tool showing stored fault codes, can point to work that wasn’t finished properly.
• Your answers. The buyer compares what you said on the phone with what they find.

A repaired panel isn’t a deal-breaker on its own. What usually costs more is a buyer finding it after you said the car had never been touched. At that point they stop pricing the repair and start wondering what else you didn’t mention. Undisclosed history is one reason an offer can drop after the inspection.

Which repair papers should you keep?

Paperwork turns “it was in an accident” into “here’s exactly what was done”. Gather these before you advertise or call a valuer:

• The repairer’s final invoice, itemised to show which panels were repaired, replaced or painted, and which parts were used.
• Your insurer’s claim number and a copy of the assessment or repair authorisation, if the repair went through insurance.
• Any written warranty the repairer gave you on the work.
• A wheel alignment printout, if one was done after the repair.
• Records of sensor or camera calibration, if the repair involved the bumper, grille or windscreen.
• SRS parts on the invoice, if any airbags deployed.
• Before and after photos, if you took them.
• The sale contract or dealer notice, if the car was repaired before you bought it.

If you’ve lost any of these, ask the repairer or your insurer whether they can send copies. Keep everything together with the service logbook, so a buyer or valuer can see the car’s whole history in one place.

How do you tell a buyer or valuer about a past accident?

Say it early, say it plainly and say it once in writing. A good description covers when it happened, what was damaged, who repaired it, whether it went through insurance, what was replaced, and what paperwork you have.

For example (a made-up message): “In March 2024 the car was rear-ended in traffic. It went through my insurer and an approved repairer replaced the rear bumper and tailgate. No airbags deployed. I have the invoice and the insurer’s claim number.”

That one message does three jobs. A valuer can price the repair into the first offer, instead of finding it at the inspection and revising the number. A private buyer can decide before they travel to see the car. And if anyone questions it later, you have a dated record of what you said.

Tell a valuer up front even if the repair was minor. A small, documented repair is a short conversation. An unexplained paint difference found on the day starts a longer one.

Deciding how to sell a car with a repair history

If you sell privately, expect most buyers to ask whether the car has been in an accident. Some will want to see the invoices, and some will walk away when they hear the answer. If the history includes a write-off, expect fewer buyers again.

If you’d rather explain it once, tell a licensed dealer on the valuation call. Sell Your Car Australia is run by a valuer who has priced cars since 1992, and you get a genuine offer by phone from a licensed dealer, not an online estimate. Tell us about any accident, repair or insurance claim on the call, so it’s part of the offer from the start. If your car has ever been written off, say so up front too: it can show on a PPSR search, and it changes what a car is worth.

If you accept, a deposit is often paid the same day, and the inspection follows at a time and place that suits you. The balance goes into your bank account, and the car is collected only after you confirm the funds have cleared. We buy cars, utes, SUVs and 4WDs that are 2021 or newer with 100,000 km or less. If yours is older or has more kilometres, send it through anyway and we’ll tell you straight away if we can help. Start with a free, no-obligation valuation, or call 1800 73 55 73.
