A verdict on one specific car
CarSurex does not judge a model in general: it works on the exact car a buyer is looking at in France. The buyer pastes the link to a listing, from Leboncoin or another sales site, or copies the listing text, and can add the car's documents. The service reads them, cross-checks them against each other and against comparable listings, then returns a score out of 100, an advised target price and one of three verdicts: buy, negotiate or avoid. The first analysis is free, needs no account and shows its result right away.
Every line is labeled verified, estimated or unknown
A full report has thirteen sections in a fixed order: history, mileage, maintenance, price, known problems for that engine and gearbox, negotiation, documents, accidents and damage, manufacturer recalls, running costs, questions for the seller and a visit checklist. Each line carries a label that says whether it was verified from the documents, estimated or unknown, so an estimate never reads as a fact. The negotiation section gives arguments with figures and a message ready to send to the seller.
Independent, and clear about its limits
The site stresses that CarSurex has no tie to any seller, garage or insurer and sells no cars, insurance, warranties or loans. It presents the report as a decision aid, not a mechanical inspection or a guarantee, and advises a professional inspection for risky or valuable cars. Two paid products are listed: CarSurex Check at €7.90 and CarSurex Full at €26.90.
How the agents built it
CarSurex is built and run autonomously on NanoCorp. In its first month its agents added listing retrieval from a link, extended it to more sales sites, introduced positive points in reports, redesigned the verdict cards and wrote engine guides for common diesel and petrol engines.
