Check an asking price.

Paste the text of a car advertisement. CarQuant matches it to the library and shows what that specification should sell for, against what is being asked. Free, and nothing is stored.

Paste the description as well as the specification table. We read only the text you paste; we do not open links, and nothing is stored.

The car

The link is all we need. We take the photographs from the advertisement ourselves.

How far will you drive it?Required

Four figures in the report move with this and none can be read off the advertisement. Our own figures assume about 5,000 km a year.

Why this changes the number

Fuel and tyres scale with distance and the free page does not carry fuel at all. Servicing is a floor rather than a rate: one happens whether the car moves or not, and a second appears once it does. Half the fault list is a distance schedule wearing a dollar sign. And the resale figure at the end of five years is a function of the odometer you put on it, which is the one input only you have.

Before you pay
What do I need to send?

The link to the advertisement and an email address. We take the photographs from the advertisement ourselves. The one thing we ask is how far you will drive it, because four figures in the report depend on it.

How long does it take?

Usually within 48 hours, because a person reads it before it goes. If the auction closes sooner, email the link to nicholas@carquant.com.au before you pay and you will hear back within a day whether it can be done in time.

Which cars can you do?

Models with recorded Australian sales. Each model's valuation page says whether a report is available on it, and the ones without an Australian sale are refused.

Is it an inspection?

No. Nobody puts the car on a hoist. The report reads the advertisement and its photographs against recorded sales. For condition, book a pre-purchase inspection, and for finance owing or write-offs, run a PPSR check.

Who writes it?

Nick Markou, who runs CarQuant. The first draft is written with AI; he checks every figure against the photographs and the sales, corrects it and signs it.

How do I pay?

By card through Stripe at the next step. The card details go to Stripe and never reach us. There is no account and nothing recurring.

The adjustment schedule the analyser applies ↓

Two layers. Model-specific rates for colour, factory options and odometer sensitivity live on each vehicle page, because they are the model. These are the layers that apply to every car: the global multipliers, and how the market treats modifications for each class of car.

Global multipliers (all cars)
How the market treats modifications on Japanese performance cars
Modifications subtract on resale far more reliably than they add. The next buyer inherits unknowns (what the tune did, what the guards hide, whether it can go back to stock) and prices that in. Two things soften every penalty below: the original parts coming with the car, and paperwork. The unmodified original is itself the most valuable option on this list.
Paint protection film (PPF)+1%
The film industry's own surveys claim 10-15 per cent. Treat that as a vendor claim: the honest effect is small and mostly indirect: a front end that never took the stone chips. On a classic it is period-incorrect and worth nothing either way.
Ceramic coating0%
Detailing, not equipment. It signals care and moves nothing.
Aftermarket exhaust (cat-back, brand-name)-2%
The most forgiven modification, and still a subtraction. A respected brand with the factory system in the boot approaches neutral; a no-name system or a missing original does not. Decats and straight pipes fail roadworthy and price like a fault.
ECU tune / flash-6%
The buyer cannot see what the tune did while it was on. On turbocharged Japanese engines with known ringland or bearing weaknesses this is the modification the market punishes hardest, dyno sheet or not, because the sheet shows output rather than history.
Coilovers / lowered-4%
Quality hardware with the factory suspension retained is a small hit. Air ride, or nothing to put back, is a larger one: the buyer prices a return-to-stock job they may never do.
Aftermarket wheels-2%
Halved with the originals in the shed, near-erased when the aftermarket set is period-correct for the car. On a classic, non-period wheels read as a car that has been got at.
Body kit / widebody / wrap-8%
Cut guards cannot be uncut. A wrap is milder, but the market prices what might be underneath it, sight unseen. Polarising builds find one buyer eventually; a valuation cannot assume that buyer.
Seats / wheel / cage changed-3%
A cage in a road car signals track life and removes back seats the market wants. Factory-catalogued buckets are the exception and belong under factory options, not here.
Internal engine work (cams, pistons, rods, stroker)-9%
The one modification a buyer cannot inspect, cannot undo, and cannot verify was done well. A dyno sheet shows output, not machining tolerances or how many heat cycles followed. Priced hardest on engines whose standard internals are themselves the collectable part.
Larger or replacement turbocharger-5%
Separated from the tune, which used to carry it silently and so priced a bolt-on and a snail as one thing. Standard turbochargers retained in the shed halve it: the car can be returned to what the record describes.
Fuel and ignition upgrades (injectors, pump, coils, E85)-3%
Individually minor and usually reversible. It matters because it is the supporting evidence for how hard everything else has been asked to work.
Non-standard clutch or lightened flywheel-2%
Often a wear item replaced with the only part available rather than a choice. Small, and smaller again where the receipt reads like maintenance.
Intercooler, intake or cooling upgrades-2%
Visible, reversible and cheap to undo, so the market barely charges for it on a modern car. On a concours-judged classic the non-original alloy in the engine bay is the whole penalty.
Resprayed in a non-original colour-6%
Distinct from a bare-metal respray in the original shade, which is restoration and can be a premium. A colour the factory never applied to that car cannot be undone cheaply, and it forecloses the buyer who wanted the one it left the line in.
Period-correct catalogue parts (Nismo, TRD, STI, Mugen, Ralliart)+2%
The one modification family with a positive sign, and only on Japanese cars, only with the boxes or receipts. The factory's own motorsport catalogue is provenance rather than modification; undocumented, it is just parts.
Rates are for this car's market class. The listing analyser applies them automatically when an advertisement mentions the work.
