Abstract: Systems and methods for providing information regarding vehicle inventory availability to users of an information system are disclosed. When generating a vehicle data page for a particular vehicle at a particular location, the information system may generate an expected duration of availability of the vehicle as a prediction of the time between listing and sale of the vehicle. When the expected duration of availability is below a threshold, a status indicator may be generated and added to the vehicle data page to alert users that the vehicle is expected to remain available for only a short period of time. An estimate of time remaining for the vehicle may also be generated and presented to users as part of the vehicle data page.
