1988 Mazda RX-7: Buy or Avoid?
The 1988 Mazda RX-7 is a fantastic driver's car with a truly unique engine, but make no mistake, it demands a knowledgeable owner and significant financial commitment. This is not a car for the faint of heart or those seeking conventional reliability; it’s a high-risk proposition that requires diligent maintenance to avoid catastrophic engine failure.

1988 Mazda RX-7 Mileage Danger Zones
The mileage windows when the 1988 Mazda RX-7 most commonly needs attention. Plan ahead, budget accordingly, and inspect before you cross each threshold.

Apex Seal Assessment Zone
This mileage is critical for rotary engines. If prior maintenance was lax, apex seal wear will likely accelerate, leading to noticeably increased oil consumption, hot starting issues, and reduced power. Turbochargers on Turbo II models m…
Engine Rebuild Risk Zone
For many RX-7s, 90,000 miles is the point where an engine rebuild becomes a strong possibility due to apex seal failure, coolant seal degradation, or simply carbon locking. This is also when major suspension, electrical, and rust issues…
High Risk / Project Car Zone
An RX-7 at this mileage has likely either had an engine rebuild or is desperately in need of one. Expect all major systems to require attention. These are typically enthusiast-owned, well-documented examples or project cars requiring ext…
