Best Model Years
All 1979-1980 (SA22C First Generation) models are generally good; condition and maintenance history are paramount over specific year.
Years to Avoid

Top Risk Areas
The systems that tend to fail first on the 1980 Mazda RX-7, with the typical mileage window when each becomes a concern. Detailed repair-cost ranges and exact what-to-check inspection notes are in the full report.
The 12A rotary engine is prone to apex seal wear, carbon buildup, and oil control ring issues. Neglect of proper oiling (pre-mixing, regular changes) leads to compression loss and eventual engine failure.
Given its age, the unibody structure, rocker panels, wheel arches, frame rails, and strut towers are highly susceptible to rust, especially in regions exposed to salt and humidity. Can compromise structural integrity.
The Hitachi downdraft carburetor can develop issues with wear, vacuum leaks, and clogging due to ethanol in modern fuels. This leads to poor idle, hesitation, and reduced performance.

Elevated Risk Zone
Many 12A rotary engines, especially if not meticulously maintained, will be nearing the end of their original service life. A rebuild is a strong possibility. Expect significant wear across all mechanical and cosmetic components.
High Risk Zone
Vehicles at this mileage are almost certainly on their second (or more) engine, or are in dire need of a rebuild. Every system will have seen extensive wear. Condition, maintenance history, and prior rebuilds are far more important than…
