How the Trust Score works
Last updated 17 June 2026
Every Trust Score on CarJio is computed by a fixed set of rules — no black box, no AI, no randomness. The same inputs always produce the same score, and every point traces back to a named rule you can see on the listing.
The two scores
Each listing carries two related 0–100 scores, shown with a band of Excellent, Very Good, Good or Fair:
- Trust Score — overall buyer confidence, combining verification, transparency and the objective facts of the car.
- Transparency Score — purely how much proof the seller has provided (documents, videos, photos and a real description).
What earns points
The Trust Score is the sum of independent rules. The main contributors are:
- Verification — a confirmed verification level is the strongest single signal. CarJio Verified™ acts as a capstone.
- Documents — registration certificate, insurance and service history that we have checked.
- Video verification — the five walkaround videos (exterior, interior, engine, cold start, odometer).
- Photo quality — enough clear, high-resolution photos (1024px or wider).
- A real description — a meaningful write-up rather than a one-liner.
- Ownership and usage — fewer owners, sensible kilometres-per-year for the car’s age, and recent model years.
- Seller reputation — the seller’s track record across their listings.
What it is not
- It is not influenced by payment or promotion — there is no way to buy a higher score.
- It is not a mechanical inspection or a guarantee of condition. It measures evidence and transparency, not the car’s future.
- It never penalises a car for things outside the seller’s control beyond the stated, visible rules.
Why “no black box” matters
On every listing you can open the Trust and Transparency panels and see the exact rules that did and didn’t apply, each with a plain-language reason. If you disagree with a score, you can see precisely why it is what it is — and a seller knows exactly what to improve.
