Methodology // evidence before mythology

How We Build a Dossier.

The goal is not to produce a universal score. The goal is to explain the ownership pattern clearly enough that a reader can make better decisions about an actual used car.

Core boundary

This page explains the ownership pattern of the machine. It cannot establish the condition of the specific car you found.

01 // Scope first

Badge, model, configuration, market.

We avoid treating a badge as one machine when generation, engine, transmission, drivetrain, battery system, trim or regional specification materially changes the ownership proposition. A claim is only as broad as its evidence.

02 // Recoverability

What happens after something goes wrong?

03 // Evidence states

Unknown stays unknown.

We distinguish reported claims, observations from sources, reasonable inferences and unresolved uncertainty. New or recently imported vehicles may simply lack enough aging history to support a mature long-term verdict. “Insufficient aging data” is a valid conclusion; it is not converted into “bad.”

04 // Recalls & campaigns

A recall is not a remote diagnosis.

A recall, service action or campaign applies to a defined population. A dossier should identify the relevant market and model-year/configuration scope from an authoritative source where possible, then direct the reader to VIN-level verification. It should not state that every individual example currently has the defect or remains unrepaired.

05 // Geography

Recoverability has an address.

Parts, warranty administrators, importers, dealer continuity, independent repair knowledge and specialist density can differ sharply between countries. We do not silently project a U.S., Mexican, European or Middle Eastern support environment onto another market.

06 // Young brands and new entrants

Nationality is not a verdict.

For young brands and recently entered markets, we examine the actual local support structure: distributor or subsidiary, dealer/service footprint, warranty terms, parts pathways, software dependence, technical-information access and evidence of continuity. Where long-term independent repair history does not yet exist, the dossier says so.

07 // The decision layer

The user remains part of the work.

The dossier gives orientation, not certification. Once a real candidate appears, the next questions concern recorded history, unresolved recalls where applicable, service documentation and physical condition. Where appropriate, a qualified physical inspection can answer questions a static page or history database cannot.

08 // Corrections

Evidence can change the file.

Automotive support networks, warranty terms, parts supply and recall status change over time. Dossiers carry review dates and sources so later reviews can distinguish fresh evidence from inherited assumptions. We prefer correcting a file over defending an old conclusion.
