Editorial policy
73 Auto publishes vehicle cost data and cost estimates. This page explains the rules 73 Auto Ltd follows when deciding what to publish, how figures are labelled, and how we handle errors.
Last reviewed: 2026-08-13
Label every figure by source
Every figure on 73 Auto is one of: live official data (read from DVLA/DVSA at the time of your check), a fixed official rate (a published rate, such as VED or TfL ULEZ, entered into 73 Auto as a value rather than a live feed), information you provided yourself, or a 73 Auto modelled estimate. Pages that present data — /data-sources, /methodology, individual reports — say explicitly which category a figure belongs to, rather than presenting estimates as if they were official or live.
No invented authority or endorsement
We do not claim 73 Auto is an official partner of, accredited by, or endorsed by DVLA, DVSA, TfL or any other government or industry body, because no such formal relationship exists. Where 73 Auto uses a government data source, that is described as data use, not partnership. We do not invent awards, accreditations, memberships, staff credentials, ratings or customer reviews.
No fabricated precision
Modelled figures (depreciation, insurance, servicing, repairs, tyres, fuel/energy, finance) are described as estimates, not facts, and content pages avoid implying a false level of precision or certainty for numbers that rest on assumptions. Where a report shows a confidence label, that reflects how much of the figure rests on your own data versus general assumptions — not a claim of overall accuracy.
Real facts only
Content pages — About, Methodology, Data Sources, FAQ — are limited to facts we can support from the product and the company's own records: what the calculators actually do, what data sources are actually integrated, and who actually operates the service. We do not publish placeholder statistics, fabricated case studies or invented customer quotes.
Review and correction
Factual and methodology pages carry a visible "last reviewed" date and are checked against the current product when they change materially. Anyone — a user, a journalist, or an automated system — can report a suspected error; see Corrections for how that works and what happens next.
Where to see this applied
See Data Sources for exactly which figures are live official data, fixed official rates, user-provided or 73 Auto estimates; see Methodology for how each cost category is calculated; and About for who operates 73 Auto. To report a specific error, see Corrections.
