SELLER FIELD GUIDE
Free car valuation in Australia: which number should you use?
A free price guide is a starting point, not a promise. Choose the method that answers your question: what similar cars are advertised for, what a dealer may offer, or what a buyer will actually agree to pay.
The short answer
- Use the same year, badge, engine, transmission and kilometres when comparing results.
- Keep advertised prices, estimated ranges and actual offers separate.
- A valuation does not require you to sell. Check what details each service asks for before continuing.
Compare methods, not just headline prices
| Method | Useful for | What it cannot confirm |
|---|---|---|
| Motorly valuation | A dealer-oriented guide from comparable dealer listings and vehicle details. | A guaranteed offer or settled sale; weak comparable evidence needs caution. |
| Carsales valuation | A vehicle-specific estimated range using Carsales internal market information. | Carsales states its estimate does not account for condition, colour or options. |
| RedBook research | Vehicle specifications and valuation research as another reference point. | That a particular buyer will pay the guide amount; check the selected product’s current scope and fees. |
| Current adverts | Seeing the asking prices and competing stock for a similar car. | Final negotiated sale prices or whether an advert disappeared because the car sold. |
| Written buyer offers | Testing what an identified buyer is prepared to pay on stated terms. | Final proceeds until inspection, deductions, finance and payment arrangements are resolved. |

Is a RedBook car value free?
Do not assume every RedBook product has the same access or price. Its specification and valuation services have different levels of detail and coverage. Check the current product before requesting a report. If you want another free benchmark, Carsales states that its online valuation is free; its selling and trade-in valuations require a signed-in Carsales account.
What Motorly’s free calculator does
The calculator uses vehicle details and comparable dealer-market evidence to produce an indicative range. No sign-up is needed for the calculator. The “Within 60s*” guide is not a deadline: extra market-listing collection can take longer. Motorly is a seller platform, not the buyer of your car, and the estimate does not commit you to a sale.
If you decide to seek real dealer offers, that is a separate step through the existing application. You provide the details required to assess the car, set your own target and choose whether an offer meets your needs.
Why two calculators can disagree
- Different markets: a dealer-buy estimate and an advertised retail range answer different questions.
- Different matches: wrong badges, body styles or drivetrains can change the comparison pool.
- Different evidence: sources, listing dates, coverage and condition assumptions vary.
- Missing details: damage, service history, options and mechanical issues may not be included.
Do not average incompatible ranges to invent a precise value. Ask what each range represents, check comparable vehicles and use real offers to test your target.
A five-minute valuation checklist
- Confirm exact vehicle identity and current odometer.
- Record service history, known faults and any finance payout.
- Check whether comparisons are dealer or private adverts, and whether prices include on-road charges.
- Read the evidence limitations; a sparse pool is a reason for caution, not confidence.
- Decide whether you want a guide only or actual buyers assessing the car.
Common questions
Is the highest online estimate the best one?
Not necessarily. A high retail asking-price guide may not reflect dealer buying costs or your car’s condition. Compare like-for-like markets and net proceeds.
Does a free valuation mean I will receive calls?
That depends on the service and the step you choose. Motorly’s calculator does not require sign-up; an offer application is separate. Read the privacy notice before sharing contact details with any provider.
Can an advert tell me what a car sold for?
No. An asking price is not a transaction price, and a removed advert is not confirmation of a sale.

Median dollar gap per vehicle
The reviewed sample covers 435 vehicles receiving an offer between 11 November 2025 and 10 November 2026. Spread is (highest − lowest) ÷ lowest, calculated only for multi-offer vehicles. Offers below $500, test and merged records are excluded. These are offers, not settled sales or a representative sample of every Australian car. The two medians are calculated separately; neither is a promised uplift for your car. A single quote is a useful starting point, not the whole market.

Use the free calculator for an indicative dealer-buy range. You can stop at the estimate or, if selling suits you, continue separately to an application for real dealer offers.
Motorly is the platform, not the buyer. Free for sellers; you set your target and can decline offers. A calculator estimate is separate from an offer application.
General information, not financial advice. Check the buyer, vehicle history, payment arrangements and written conditions independently. Market estimates and advertised prices are not guaranteed sale proceeds.
