CarMax Vehicle Inventory API

The CarMax Vehicle Inventory API exposes details about all used vehicles currently in CarMax's nationwide inventory, including year/make/model, trim, mileage, price, exterior and interior attributes, photos, and stock number. The API powers carmax.com's search experience and the Vehicle Detail Page. It is consumed internally and surfaced to customers through CarMax's own products rather than opened as a public partner feed.
