The true cost of hiring a car at one airport: per-day price for the car alone, with a second driver, with full cover, automatic, no-deposit (from + typical); by pick-up month; second-driver fees; deposits; debit-card acceptance; desk closing times and out-of-hours fees; policies; Brain's pick per car size (the well-rated supplier that is usually cheapest here, measured - say 'usually'). Use when someone asks what car hire really costs at one airport, or about deposits, fees or desk hours there.
DiscoveredA link for the PERSON to open: live prices for their exact dates and needs, ranked by the total they will actually pay, where they can book. Use whenever the person has dates and wants to see or book cars. Works for any place; coverage says whether Car Rental Brain has measured it (not_measured: no figures of ours exist there - say so, quote none).
DiscoveredRank airports by real cost (car only / with driver / with cover), typical deposit, debit-card friendliness or late desk hours. Use for 'where in Spain is car hire cheapest in March?' or 'which airport is best for a debit card?'
DiscoveredWhat Car Rental Brain measures, how fresh it is, and which airports/countries are covered. Use first when unsure whether a place is covered.
DiscoveredAirports we measure, with the typical rental price per day. Filter by country. Use to find an airport id or to list what is covered in a country.
DiscoveredONE call for a car-hire question at one airport: the usual total for the person's dates split into rental, second-driver fee, cover and out-of-hours fee (deposit shown separately as a card hold), the suppliers that usually suit their needs with each requirement marked meets / unverified and its evidence (debit card, deposit limit, automatic, 7 seats, car size, cross-border - checked together, company by company), and the correctly dated search link to book. Measured history, not live offers. Use first when the person gives dates or needs (debit card, deposit limit, second driver, late arrival).
DiscoveredPer supplier at an airport: typical price per day, second-driver fee, full-cover price, deposit held, whether the desk takes a debit card, and customers' desk review scores. Use when the person is choosing between suppliers at one airport or asks about a named supplier.
