Abstract: An electronic system (30) includes several computers (32, 34, 36, 40) in data communication with one another. An electronic window sticker computer (EWS) (32) resides at each vehicle (28) on a dealership lot (22). The EWS computers (32) communicate with the remainder of the system (30) through an RF network (54). A book-in process (78) and/or a lot manager process (146) form a VIN record 96 for a vehicle (28) to which an EWS (32) has been assigned. The VIN record (96) includes a robust set of promotion presentation data (74) that are presented at the EWS (32) using a plurality of screens (112). User inputs are collected at the EWS (32) and routed to the lot manager process (146). Updates to the promotion presentation data (74) may be made frequently, and some updates may be made automatically (204). The updates are reflected at the EWS (32) in real time.
