Method and limits
THE GEM tracks listings published by third-party sellers and marketplaces. Every figure on this page carries its provenance: SOURCE VERIFIED means the number is published by the seller and re-checked by our daily crawl; THE GEM DATA means it is computed from the cars we currently track, and the sample size is always stated; ESTIMATED means it is our own calculation, not an observed transaction; MODEL KNOWLEDGE applies to a generation, never to the individual car shown.
We do not publish vehicle history, provenance, ownership or factory specification unless a source states it. Where a fact is unknown, this page says so rather than filling the gap.
This page is a market observation, not investment advice and not a mechanical appraisal. No car should be bought without an independent pre-purchase inspection.
