01
Data collection
We track the market by building a structured archive of prices, mileage and condition data for every model we cover.
02
Scoring model
Each model receives an appreciation score from 0 to 100, calculated by our proprietary algorithm which, by combining data and artificial intelligence, identifies the probability of appreciation over time.
03
Classification
Based on the score, every model is classified as BUY, WATCH, or AVOID — a simple signal to help collectors prioritise their research and act with confidence.
04
Collector knowledge
Beyond numbers, each model page includes known issues, recommended vintages, inspection guides, and red flags — curated by our AI and reviewed by enthusiasts.
