CarQuant for business

Collector-car prices for the businesses that lend, insure and trade.

Insurers, lenders, dealers and auction houses all have to put a figure on collector cars, and the usual sources are asking prices and guide books. CarQuant prices them from what the same cars have sold for in Australia, with the sales attached and the accuracy published.

Who it is for
Insurers and brokers

Agreed values checked against recorded Australian sales, with the sales attached, when a policy is written and when it renews.

Lenders and financiers

A figure for the car itself before the money goes out: the value, the range around it, how many sales carry it and how long one takes to sell.

Dealers

Stock and trade-in pricing against the Australian record, and the listing report on any car before it is bought.

Auction houses and brokers

Estimates and reserves set against results for the model, including the lots that did not sell.

What a business gets backDrawn live from the record

These are the models the library knows best right now, each as one file: the value, where most sell, its market, how long one takes to sell, and the sales it stands on. Every model in the library has the same file, and every figure in it can be traced to a sale.

Where the evidence is thin the file says so, and the 88 models with no Australian sale behind them are refused for paid work.

What is available
Values and the evidence under them

Every model in the library, 244 today, with its value, its evidence grade, its range and the counted sales behind it.

The sales ledger

631 completed Australian sales with the date, place, distance and the note that decides whether each one counts.

The CarQuant Index

The market line for all collector cars and for each segment with enough evidence, built on 430 sales and refitted on every result.

Listing reports for teams

The $249 report on any advertised car, for teams that need more than a few a month.

Prices called before the hammer

A published figure on a lot before it closes, graded against the result afterwards, the way the track record is.

What is supplied, how it arrives and on what terms is agreed with each business. Tell Nick what you price and he will set out what fits.

Why the figures hold up
Independent

CarQuant takes no money from sellers, dealers or auction houses to price, list or promote a car, and no commission on any sale. It is paid by the people who order its reports.

Only completed sales count

Asking prices, passed-in lots and withdrawn lots are recorded on the model's page and never counted. Every value shows the sales under it by date, place and price.

The accuracy is published

Prices are called on lots before the hammer and graded against the result: a typical miss of 8.4 per cent across 26 cars so far, the bad ones included.

Price evidence and opinion

CarQuant is not a certified valuation. Where a certified valuation is required by law or by a policy, its evidence sits beside one.

How it starts
  1. 1
    Say what you price

    The cars, roughly how many, and what the figure is for: a policy, a loan, stock or a reserve.

  2. 2
    Nick sets out what fits

    From the library, the ledger, the index and the reports, and in what form it would arrive.

  3. 3
    Figures with the sales attached

    Every figure comes with the sales it stands on and the range around it, so it can be checked.

Questions businesses ask
Is it a certified valuation?

No. CarQuant publishes price evidence and opinion. Where a certified valuation is required by law or by a policy, CarQuant's evidence sits beside one.

Where do the sales come from?

Published Australian results, 631 of them counted today, from Collecting Cars, Shannons, AutoMarkets, Lloyds, Grays and others. Each is tied to a date, a place and a car, and the sources are counted on How the numbers are made.

How current is it?

The newest counted sale is 6 Oct 2026. Results are added as they are published, and the CarQuant Index refits on each one.

Can a list of cars be priced against it?

Every model in the library has a value, a range and its sales, so a list can be read against it model by model. Models with no Australian sale are named as such, and Nick says what can be done on the rest.

What does it cost?

There is no business price list. It depends on what you price and how often, and Nick sets out what fits once you tell him. A single listing report is $249.

Who is behind it?

Nick Markou, who runs CarQuant from South Australia. CarQuant takes no money from sellers, dealers or auction houses to price, list or promote a car, and no commission on any sale. It is paid by the people who order its reports.
