READ THE SIGNAL

Hidden Value, explained.

Year-specific evidence leads. Broader model history adds context.

Calculate a historical discount separately for the selected model year and for all available years of the same manufacturer, model, declared trim and currency.

Hidden Value = 70% × year discount + 30% × all-years discount

Turn off “Include year-specific evidence” to use the all-years model discount at 100% weight. In that mode, year-specific history does not affect the score or ranking. Vehicle groups and their price histories remain available by year.

Each component compares median published sold prices in 2025–2026 with 2022–2024, within each anonymous archive. Both periods need at least five eligible sales. Positive discounts are capped at 100, while increases contribute zero. Qualifying archives are weighted by the smaller period count, capped at 30.

Missing components contribute zero; their weight is not redistributed. A vehicle with only broader history can score up to 30. With no qualifying history in either component, the vehicle remains unscored. Vehicles are always ranked by Hidden Value, highest first.

Read the evidence

The all-years pool includes the selected year, so the two sample counts overlap. Broader pools may span generations. Condition, mileage, modifications, authenticity, inflation, vehicle mix and fee changes are not adjusted. This is a historical-discount research screen, not intrinsic value or a forecast.

Price graphs show one solid line per anonymous archive and a dashed blended annual median. The blend pools eligible sales, so higher-volume archives contribute more observations; it is not an average of archive medians. Currency vehicles remain separate.

Remove year

Check “Remove year” to combine model years into one manufacturer/model/declared-trim/currency group. Counts, pooled sale statistics, archive lines and the blended trend all follow that combined group. Hidden Value uses the all-years signal at 100% weight. Uncheck it to restore separate year groups.

Manufacturer counts

The make selector includes only manufacturers with active vehicle groups under the other filters. Counts refer to model-year/trim/currency groups, not unique physical cars. Unknown manufacturers remain in review.

Open a vehicle to inspect both score components. Archive filters select vehicles represented in that archive; vehicle statistics continue to cover every archive in the selected group. Dates retain their available precision.
