Sources differ: Mazda's December 2003 press release limits the Roadster Turbo to 350 units for Japan, while Mazda's MX-5 chronology says 300 units.
Independent counts (e.g. engine and colour) are never combined into a calculated figure. Surviving examples are never presented as original production.
History
