Listings buyers can trust, sight unseen.
Steer AI, the AI infrastructure for the used-car economy, adds a verified condition report to every listing — engine, battery, suspension, brakes and a 360° exterior, read from the car itself — so buyers can commit to a car they haven't seen.
The trust gap online
Millions of cars change hands, most on a seller's word.
Buyers shortlist from a screen. Without proof of condition they hesitate, haggle or travel to see the car, and the sale slows down.
Used cars sold in France in 2025, up 0.8% on 2024.
Of French people see a reconditioned used car as more reliable than a traditional one: buyers pay for confidence.

From inspection to sale
The report travels with the listing.
Four moments where evidence replaces guesswork for the buyer.
01Inspect before you list
The seller or a partner runs a 360° capture and plugs in the device. Every car on the marketplace follows the same protocol.
02Read how the car drives
DeepDiag measures the engine, battery, suspension and brakes on a short road test — what photos alone can't show.

03Let buyers compare on evidence
A verified badge, the condition report and a market price sit on the listing. Buyers shortlist on facts, not on adjectives.
04Close the sale with fewer surprises
The buyer collects the car they read about. The dated report answers questions before they turn into disputes, and Steer OS keeps it in your platform.
