This listing has one pricing dimension: Product Access (Units), offered at no cost. It grants subscribers access to the Exotic Car Market Index (ECMI) data. There are no tiers, instance sizes, or usage add-ons to choose from. You get a single access option billed under the free model. The underlying data covers collector and classic car auction results and private-sale records, refreshed continuously. Because only one dimension exists, pricing does not scale by seat, volume, or usage. Access is granted uniformly to any subscriber through this single unit.
Top-of-mind questions for buyers
What does one unit of Product Access grant me?
One unit grants a subscriber access to the Exotic Car Market Index (ECMI) data. It maps to a single access grant, not a seat, server, or usage quantity. Because it is billed under the free model, the unit carries no cost regardless of how much data you view.
What kind of data does this access cover?
Access covers collector and classic car market data, including auction results and private-sale records. The underlying dataset tracks realized transaction prices across many car makes and eras, refreshed continuously as new sale results come in.
Does my cost change if my usage or team size grows?
No. This listing has a single free dimension with no tiers, seats, or usage meters. Nothing triggers a cost change because access is granted uniformly under the free model. Your bill stays the same regardless of how many people use it or how much data you query.
