Serials by Year

Model YearProduction DateSerial NumberNotes
SA/FB
19793/78-6/79SA22C-500001~SA22C-566640There are no duplicate serial numbers,
e.g. if there is a SA22C-501234, then there is no FB*31-501234.
It appears that in 1980 and 1981 low-spec export models (base, L, DX, ...) and all Japanese domestic models got SA22C serials whilst high-spec export models (GLS, SDX, ...) got FB*31 serials.

Mazda manual info suggests Convertible serial nrs are continuous (despite 1990 facelift), although I've seen at least one (M, 1991) US Convertible with a 90**** serial number.
After Mazda announced there would be no FD Convertible made, so many orders for FC Convertibles were placed that production continued well into 1992.
In all 22.418 Convertibles were built (22.268 up to 8/92 followed by 150 'Final Edition' versions for Japan only).
