What's the difference between the autobiz rating and the Argus rating?

Calculated using an algorithm, our rating is a market value, derived from the daily analysis of 2 million classified ads published by professionals and private individuals. The argus rating is calculated differently: argus applies a mathematical discount (depreciation) to the new catalog price, and they adjust their values with experts & manufacturers around a table, agreeing on prices. Our value is 100% statistical, calculated automatically from prices actually observed on the market. Non-statistical values proposed by our competitors are mathematical discounts from the new list price, adjusted following expert feedback.
