Sources & method
Evidence before confidence. Every claim is graded, conflicting numbers are preserved rather than averaged, and unknown/disputed/not-applicable are kept distinct.
How to read the numbers
Each key figure carries a confidence badge — High, Medium, or Low. A number without a period, market and accounting basis isn't ready, so where a figure is disputed (like the 1969 Z/28 total, cited as both 19,014 and 20,302), both values are shown with the conflict called out rather than a false single answer.
“Rare” is an editorial conclusion that requires a defined denominator and a source that counts the exact car. We never manufacture a “1 of N” claim by multiplying option percentages together.
Assurance levels
Vehicle conclusions are labelled decoded, factory-record-backed, or physically inspected — three separate claims with separate evidence. A rule-based VIN decode is never called “authenticated,” “certified,” or “matching numbers.”
