Hermes Data

A daily-refreshed census of live retail vehicle listings across every retail rooftop in the US and Canada — one normalized record per listing carrying decodable VIN, year/make/model/trim, new vs certified status, odometer, current asking price, MSRP and implied discount, mechanical and cosmetic specs (engine, transmission, drivetrain, colours, features), plus the specific dealership and location each vehicle sits at. Every listing carries first_seen and last_seen timestamps, so the corpus doubles as a continuous price-change and inventory-churn time series: markdowns, listing appearances and disappearances are all observable per VIN per day.
