Why a car offer drops after inspection, and how to prevent it

An offer usually drops after an inspection because the inspector finds something the buyer hadn’t priced in: damage or a fault you didn’t mention, a missing key, gaps in the service history, or more kilometres than you quoted. A buyer can also try to cut the price after you’ve handed the car over, so keep the car and the signed transfer until the full agreed amount has cleared in your account. Describing the car accurately, in writing, before you accept leaves a buyer far less room to cut the price.

This guide is about what happens after you’ve accepted an offer. If your problem is the gap between an online estimate and the first real number, start with why online valuations and real offers don’t match.

Why would a buyer lower an offer they’ve already made?

Instant online offers and phone offers are usually made before the buyer has seen the car in person. The buyer prices it from what you tell them and what your photos show: the make, model, variant, year, kilometres, condition and history. The inspection is where they check that description against the real car.

If the car matches, the number has no reason to move. If it doesn’t, the buyer reprices for the difference. Some instant online offer services say on their own websites that an offer can be adjusted or revised after the car is inspected. Reviews of online car-buying services include complaints from sellers whose price was cut after the inspection, including one seller who says the cut was for scratches and kerb rash they had disclosed before the first quote. One online buyer’s public reply to that kind of review says the offer holds when the seller’s answers were accurate and nothing was left out.

The reasons buyers give for a lower price fall into three groups:

• The car isn’t as described. Undisclosed damage, a warning light, one key instead of two. Usually fair.
• Something nobody asked about. Worn tyres, a windscreen chip. Whether it’s fair depends on what you were asked and what you said.
• Nothing to do with the car’s condition. Colour, popularity or “the market”. The inspection didn’t reveal any of these, so they’re hard to justify afterwards.

What does an inspector find that changes the number?

Inspectors cover much the same ground on every car. Our guide to what gets checked when a buyer inspects your car goes through it item by item. These are the findings that can lead to a revised offer, and how to get ahead of each one:

A warning light that comes and goes may be off on the day, but an inspector’s scan tool may still find stored fault codes. If a light has appeared in the past few months, say so before the inspector finds the code.

What if the kilometres, keys or service history don’t match the call?

These cause friction because they’re facts, not opinions. Nobody can argue that a car has two keys when it has one.

Kilometres. The offer is built on the odometer reading you gave. If you drive to work every day between the call and the inspection, the reading goes up. A small increase is expected, but tell the buyer if there’s a long gap or a road trip in between. Some buyers also publish kilometre limits. We buy cars with 100,000 km or less, so if yours is close, give us the exact reading on the call.

Keys. Saying “two keys” on the phone and producing one at the inspection gives the buyer an easy deduction, because they’ll have to replace the missing key. Find the spare before the call, or say up front that you only have one.

Service history. “Full service history” should mean every scheduled service done on time and recorded, in a logbook or a digital service record. If one service was late, done by a workshop that didn’t stamp the book, or skipped, say so. If the records are digital, ask the dealer that serviced the car for a printout so the inspector can see it on the day.

Variant and options. If you described the car as the top model and it’s a mid-range variant, or an option you mentioned isn’t fitted, the price was built on the wrong car. Check the badge and your purchase paperwork before the call.

Is colour or “not popular” a fair reason to cut the price?

A fair reason is new information about the car. An unfair one is something the buyer knew, or could easily have asked about, when they made the offer. Colour is the clearest example, because it’s in every photo you sent. One seller’s review of an online car-buying service says they were told after the inspection that their colour was “not popular”. If the colour mattered, it belonged in the first number.

The market is a closer call. Used prices do move: Datium Insights’ weekly market update of 12 October 2026 recorded used vehicle prices down 3.1% over the past week. That’s why it matters how long an offer is valid for: some instant online offer services say theirs are valid for seven days. Inside that window, the market isn’t a reason to change the price. After it, a fresh number is reasonable.

Use this decision guide to judge the reason you’ve been given:

A worked example (hypothetical). You tell the buyer about a scratch on the rear bumper and send a close-up photo. At the inspection, the inspector notes the scratch and a cracked windscreen you hadn’t noticed. The scratch was already in the price, because you disclosed it. The windscreen is new, so a fair revision covers the windscreen only. If the revised offer also takes something off for the bumper, push back with your photo and the date you sent it.

What should you tell the buyer before the inspection?

Disclosure is your best defence against a price cut. Anything you’ve told the buyer in writing before you accept should already be in the price you agreed, so they can’t fairly take it off again. Anything you leave out gives them a reason to reprice.

Ideally before the offer is made, and at the latest before you accept, send the buyer a short message that covers:

• Every dent, scratch, chip and kerbed wheel, with photos
• Any warning light that’s on now or has been in recent months, and any fault you know about
• Accident damage and repairs, including insurance repairs
• Whether the car has ever been written off
• How many keys you have
• What service history exists, and the date and kilometres of the last service
• Today’s odometer reading
• Modifications and accessories, and anything you plan to remove before the sale
• Any finance owing, and who the lender is
• Smoke, pet or other odours

Write-offs need particular care. Written-off status can show on a PPSR search, so a buyer who runs one may find it anyway, and it changes what the car is worth. For how damage history affects price, see selling a car with accident history.

Disclosure isn’t only about price. In Western Australia, Consumer Protection warns private sellers that they may be held liable if they know about a serious defect and don’t tell the buyer. It also says private sellers must tell the buyer about any finance owing on the car.

Keep a copy of what you sent, with the date. It’s your proof that an item was already priced.

Can a buyer cut the price after you’ve handed the car over?

They can try, which is why you shouldn’t let it get that far. If the car, the keys and the signed transfer go before the money arrives, a buyer who then “finds” a problem has your car and you have a dispute.

The rule that prevents it is simple: the car stays with you until the full agreed amount has cleared in your account. Consumer Affairs Victoria tells sellers not to sign any document that transfers ownership until they’ve received their payment or trade. It also says a Victorian licensed motor car trader must pay you for your car before trying to sell it. WA Consumer Protection’s advice to private sellers is the same: make sure the money has transferred before you hand over the keys.

Here is the order that keeps you in control:

1. You accept an offer based on an accurate, written description.
2. The buyer pays a deposit, if they offer one.
3. The car is inspected.
4. Any revised offer is agreed or declined, before anything else happens.
5. The balance is paid into your bank account.
6. You confirm the funds have cleared.
7. The car, keys and signed paperwork are handed over.

The price should only ever change at step 4. For how different buyers time their payments, see paid before pickup or after handover.

The price has changed: what can you do?

A revised offer is a new offer, and you’re free to say no to it. Before you decide:

1. Ask for the reasons in writing, item by item. “General condition” isn’t a reason. “Windscreen cracked, needs replacing” is.
2. Check each item against what you disclosed. Anything you sent in writing before you accepted was already priced.
3. Get your own quote for any repair. If a deduction is far larger than what a repairer would charge you, say so.
4. Counter with the items you accept. Agree to fair deductions for genuine surprises and decline the rest.
5. Read your agreement before you walk away. If you’ve taken a deposit, the agreement you signed decides what happens to it if the sale doesn’t go ahead. Our guide to car sale deposits covers what those terms should say.
6. Get another genuine offer. A second number from a licensed dealer helps you judge whether the revised price is fair.

If a buyer won’t explain a cut, or the reasons are ones they knew from the start, that tells you something about how the rest of the sale would go.

Before you accept your next offer

The best protection against a cut after the inspection happens before you say yes. You want an accurate description in writing, a buyer who explains how their price was built, and a payment order that keeps the car with you until the money has cleared. Ask any buyer, us included, what happens if the inspection finds something that wasn’t discussed.

If your car is 2021 or newer with 100,000 km or less, you can get a free, no-obligation valuation from Sell Your Car Australia. We’re 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. If you accept, a deposit is often paid the same day and the inspection happens 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. No fees come out of the offer. If your car is older or has more kilometres, send it through anyway and we’ll tell you straight away if we can help. You can also call 1800 73 55 73.
