1988 Mazda RX-7 (FC Turbo II) — Should You Buy One?

Typical asking price: $12,000–$30,000. There are 3 high-severity known issues you need to know before handing over a check.

Kestrel Take

The FC is the affordable rotary RX-7 and a rising classic, especially the Turbo II. Same rotary rules apply: seals wear, heat kills, and a bad tune ends it. It's simpler than the FD but no more forgiving of neglect. Compression and rebuild history are the entire decision.

What we checked

No public record to reconcile against

We don't yet have a public record to check this one against. Federal complaint records thin out badly on older vehicles, so there is little to check against. What follows is our own write-up, and it has not been reconciled against an official record. Treat it as a starting point, not a verdict.
