About CarQuant

A price record for Australian collector cars.

Most collector cars in Australia change hands with no public record of the price, so buyers argue from asking prices. CarQuant keeps the record: every value comes from completed Australian sales, and every price it calls before an auction is graded in public afterwards.

Why it exists

A buyer looking at a collector car in Australia can usually find twenty asking prices and no sale prices. An asking price is where a seller starts, and a car can sit at one for a year. The sales that do happen are scattered across auction houses, results pages that close behind a login, and private deals nobody records.

CarQuant gathers the completed sales, ties each one to a model, a date, a place and a distance, and prices from those. The free library is the record. The listing report applies it to one car in one advertisement, and the same record is open to the businesses that lend against, insure and trade these cars.

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.

The record, year by yearCounted sales by the year they closed

504 of the 631 counted sales closed in the last five years, which is where the values and the index draw most of their weight.

* 2026 to date. 5 counted sales carry no year and are not drawn.

The rules the numbers follow
  1. 1
    Nobody pays for a figure.

    No seller, dealer or auction house pays CarQuant to price, list or promote a car, and nothing is earned on a sale.

  2. 2
    Only completed sales count.

    Asking prices, passed-in lots and withdrawn lots are recorded on the model's page and never counted.

  3. 3
    Every value shows its sales.

    Each one is listed under the value it supports, by date, place and price.

  4. 4
    Prices are called before the hammer.

    Each call is published while the lot is still running and graded in public once it closes.

  5. 5
    No sale, no report.

    A model with no Australian sale on record says so, and the paid report is refused on it.

  6. 6
    Values move by hand.

    When a value changes, the reason is written into the evidence on the model's page.

  7. 7
    The working is public.

    The method, the accuracy and the errors are published in full.

Nick records the sales, sets the values, publishes the calls and signs every listing report.

The first draft of a report is AI-assisted. He checks every figure against the photographs and the sales, corrects it where the evidence demands, and signs it.

Questions about a car, the method or the data go to him directly, and so does anything about the CarQuant Index.
