Como funciona
Cada alteração de estado requer um gatilho documentado. Esta é uma demonstração.
Submit the car
The seller submits the car with photographs, documents and a written statement of what is known and what is not.
Editorial review
We check completeness, rights and plausibility. Approval is not an inspection and does not confirm the description as fact.
Format and reserve
Auction, buy-now, price proposal or confidential auction — and a reserve if the seller wants one. A reserve only changes with documented consent.
Bidding
Direct bids and maximum bids, published increments, hidden maximums, anti-sniping extension, server time as the only clock.
Settlement
Contact established, invoicing, payment confirmation, handover, seller participation. Every state needs a documented trigger.
Auction mechanics (demo rules)
Regras de licitação
Maximum bids
You enter the highest amount you are willing to pay. The system bids the smallest amount needed to keep you ahead, up to that maximum. Other participants never see your maximum — they see the resulting price only.
Equal maximums
If two maximum bids are exactly equal, the earlier bid keeps the lead. This is deterministic and applies without exception.
Anti-sniping
A bid within the last 120 seconds extends the auction by 120 seconds, up to 20 extensions. The countdown you see is informative; the server clock decides.
Reserve
A reserve is not published. If it is not reached, no sale. A reserve can only be lowered with documented seller consent, recorded in the audit log with old value, new value and consent note.
Concurrency
All writes run in a serialized transaction, so two bids arriving at the same moment cannot produce contradictory results or a double award.
Services
Transport, storage and appraisal are planned. No partner is contracted and no service is available.
Transport
Planned function, not available. No transport partner is contracted, and we do not name one to look bigger.
Storage
Planned function, not available. Storage would be arranged with named providers and clear liability before it is offered.
Independent appraisal
Planned function, not available. An appraisal is a statement by an independent expert — not something a platform can badge onto a listing.
