Research standard

Facts first. Fit second. Rankings never for sale.

How Car Dealer Vendors discovers the market, resolves companies and products, grades evidence, handles changes and protects editorial independence.

01

Discover

Build the universe from trade-show directories, expert taxonomies, OEM materials, corporate records, vendor sites and dealer operator leads.

02

Resolve

Separate the legal company, active brand, product, edition, market, former name, owner and acquired or sunset record.

03

Verify

Capture a dated source for each material fact. Integration claims require scope; logo walls are discovery leads only.

04

Review

Check applicability, conflicts, language and decision usefulness. Thin records remain discovery-only until they meet the template standard.

05

Publish

Show evidence status, review date, limitations, next action and a precise correction path on the same page as the claim.

06

Maintain

Track acquisitions, rebrands, launches, sunsets, OEM programs and stale dependencies. Propagate corrections to dependent records.

Evidence grades

A — controlling

Official documentation, signed factual questionnaire, regulator, standard, direct test or both integration parties.

B — corroborated

Qualified operator record plus multiple credible sources, published with limitations.

C — discovery

Single vendor claim, directory association or moderated observation that requires confirmation.

D — unusable

Anonymous accusation, scraped summary without source, or AI-generated assertion. Never published as fact.

What the three record statuses actually mean

Verified means the company’s identity and its published service scope were checked against that company’s own primary source on a stated date, and the record carries a packet naming what that source established. It is a statement about our research, not about the product. It does not mean the product is good, that it will work in your store, that a price was checked, or that any integration it names was confirmed. Where a provider’s own site did not name a product the record lists, the packet says so rather than glossing it.

Reviewed means scope was mapped from current provider and market sources without a dated packet behind it. Individual claims may still be one-sided, because they came from one side. Directory means the company is recorded so the market map is honest about its size, with no product, availability or compatibility claim attached — those records are excluded from search indexing for exactly that reason.

How a conflict between sources is resolved

A provider’s own current statement controls facts about itself: what it is called, what it sells, who owns it, where it operates. A third-party directory, a conference listing or a press summary is a lead to check, never the controlling source. When an acquirer and an acquired company describe a relationship differently, the acquirer’s dated announcement controls. When no source states a fact, the field says the fact is not established instead of carrying an inference — a market recorded as “global” because a summariser inferred it is worse than a market left blank, and that failure has happened here and was corrected.

What this directory refuses to publish

Some of these are stated as limits on us rather than on the reader, because a directory is only useful if its refusals are predictable.

  • A ranking, a score or a “best” of anything — including one generated from our own data
  • A price, a discount or a contract term for a product, unless the provider publishes it
  • An integration described as working without the scope, direction and confirmation date behind it
  • A quality, performance or outcome claim about any provider, from any source
  • An anonymous complaint, or a named one we cannot check
  • Nonpublic dealer financial or operational data

How to check any of this yourself

Every claim above is meant to be falsifiable from the outside. Each company record shows its status, the date, and — where a packet exists — the source URL that was checked. The source ledger lists the starting sources used for discovery and taxonomy. The change log records material corrections with their dates, so a fact you cited can be traced to what it said when you cited it. The machine-readable export carries every record with its evidence status, its dated source, its corporate parent and an explicit flag where a product’s evidence is inherited from its company rather than checked at product level. And market coverage states what is missing, because a coverage claim without a gap list is a marketing number.

Where this standard is not met yet

Stating the standard is not the same as having reached it everywhere. Most product records inherit their company’s evidence rather than carrying a product-level check; the export flags each one so nobody reads inherited evidence as an audit. Most companies in the directory are at Directory status and are excluded from indexing. The integration graph is small relative to the market it describes. These are recorded on the coverage page with numbers attached rather than left for a reader to discover.
