AutoYesNo UK · launch

Buying a used car in the UK?
Know if it's a YES, NO or NEGOTIATE before you pay.

Paste the advert, add the registration, mileage and price, and AutoYesNo checks the deal, highlights risks, and gives you negotiation arguments before you contact the seller.

  • No card for the free essai

What AutoYesNo checks

Eight signals translated into one decision.

Each card maps a specific input we receive to a specific risk we surface. No opaque score, no claim of detecting every fraud — just clear translations of what your inputs tell us.

  • Price fairness

    Asking price vs comparable adverts and well-known price-anchoring patterns.

  • Mileage consistency

    Stated mileage versus the car's age and the MOT history you paste in.

  • MOT / history risk

    Advisories, fails, write-off references, missing-MOT gaps — interpreted in plain English.

  • Seller red flags

    Cash-only, delivery before viewing, deposit pressure, V5C missing, and similar wording.

  • Negotiation power

    Specific arguments to use, with a typical £ range you can ask off the asking price.

  • Questions to ask

    The exact questions to put to the seller before you book a viewing.

  • Documents to verify

    V5C, service history, MOT certificate, identity match — what to check on the day.

  • Final decision

    A clear YES / NO / NEGOTIATE with one recommended next step.

Why a free MOT check isn't enough

The data is there. The decision still isn't.

A free MOT check can show useful information, but it does not always tell you what it means for your decision. AutoYesNo helps translate the advert, the price, the mileage and the MOT / history signals into a simple decision: YES, NO or NEGOTIATE.

  • Reads the advert text for the patterns that hide real problems.
  • Cross-references mileage against the age of the car.
  • Interprets MOT advisories and fails in plain English, not jargon.
  • Hands you the negotiation arguments and the questions to ask.

Sample preliminary verdict

  • Mileage · Medium
  • MOT history · High

MOT advisories on suspension and tyres in two consecutive years. Negotiate £400-£600 off the asking price or ask for a written confirmation that the work has been done before viewing.

FAQ

Common questions from UK buyers.

How does AutoYesNo help UK used-car buyers?+

You paste an advert URL or text, the registration, the asking price and the mileage. AutoYesNo highlights price anchoring, mileage inconsistencies, seller-side red flags and any MOT / history wording you provide, then returns a clear YES / NO / NEGOTIATE verdict with the specific negotiation arguments to use. It's decision-support for the buyer, not a black-box score.

Is AutoYesNo a car valuation tool?+

Not exactly. A pure valuation tool only tells you a number. AutoYesNo looks at the price in context — alongside the advert wording, the mileage profile, the MOT signals and the seller behaviour — and translates the whole picture into a buying decision.

Does AutoYesNo replace a mechanic inspection?+

No. AutoYesNo gives you decision-support before you contact the seller and during negotiation. A pre-purchase inspection (AA, RAC or an independent garage, typically £99-£200) remains the right step for the final mechanical check.

Can AutoYesNo check MOT history?+

AutoYesNo does not connect to DVSA or GOV.UK. You can run the free official MOT history check yourself on check-mot.service.gov.uk and paste the result into the form — AutoYesNo interprets the advisories, defects and fail history in plain English and folds them into the verdict.

What does YES / NO / NEGOTIATE mean?+

YES means no obvious red flag in the elements you provided — usually safe to book a viewing and inspect. NEGOTIATE means there's at least one significant signal that justifies a price reduction or extra proof before paying. NO means two or more high-risk signals were found — step back, ask for written evidence, or walk away.

What is included in the free essai?+

One free preliminary check, no card required. You get the YES / NO / NEGOTIATE verdict, four risk levels (price, mileage, MOT / history, seller), the main red flags surfaced, the first negotiation arguments and a recommended next step.

What is included in the €7.99 3-day pass?+

Up to several analyses across 3 days, with the full report each time: complete price fairness analysis, mileage consistency check, MOT / history interpretation, seller and advert red flags, negotiation script, questions to ask, documents to verify, and the final recommendation.

What is included in the €12.99 14-day pass?+

Everything in the 3-day pass, extended to 14 days — built for active buyers who are comparing multiple cars. Full decision reports, price + risk + negotiation analysis, PDF report when available, priority queue for serious buyers.
