Known repair windows
What MX-5 Miata owners actually run into
Mileage ranges where these repairs typically show up. Buying above a window is not automatically a pass - it just needs to be priced in.
Clutch wear (manual transmission)
medium severity60,000-130,000 mi · $1,000-$1,800
Enthusiast/track driving accelerates clutch and flywheel wear on the 6-speed manual; the popular gearbox in this model.
Elevated oil consumption (2.0L Skyactiv-G)
medium severity30,000-100,000 mi · $0-$1,500
Some ND 2.0L engines consume oil between changes; monitor the dipstick, especially on track-used cars. Range = monitoring vs. valve-seal work.
Soft-top rear window / seal wear & water intrusion
medium severityAny mileage · $300-$1,500
Weather seals and the fabric/rear window degrade; leaks cause carpet/floor rust faster than any mechanical fault. Inspect and treat seals annually.
Rear differential / wheel-bearing whine
medium severity80,000-150,000 mi · $400-$900
RWD driveline develops diff or bearing whine at higher miles; more common on hard-driven cars.
GDI intake-valve carbon buildup
low severity70,000-120,000 mi · $400-$700
Direct-injection carbon on intake valves; walnut-blast as needed.
Operator notes

Factory 0W-20 full synthetic, 7,500-mi normal interval; 5,000 mi for track/spirited use. Manual gear oil ~30k normal (15-20k if tracked). Annual soft-top seal inspection is the single most valuable upkeep item. 2024-2025 US shop pricing.
