Tap any dot on the chart to see its scores.
- Brand reliability
- Consumer-survey composite — JD Power · WhatCar · Consumer Reports. Same score for every variant of a given make.
- Resale strength
- 100 − 3× annualised tangible-decay (COE-stripped). Fitted from each variant's asking-price-by-age regression then averaged at model level.
- Peer set
- Every same-segment model with ≥5 active PARF listings whose variants fit a depreciation curve. Practicality isn't plotted — it's a body-shape constant within the segment, so it would be the same for every dot.
- Quadrants
- The crosshair marks the segment median on each axis. Top-right (Safe Bets) is strong on both; top-left (Hidden Gems) holds value above what the brand reputation suggests; bottom-right (Bargain Buys) is well-built but depreciates fast — buy cheap; bottom-left (High Risk) is soft on both.

What's good
- Documented rotary-specialist service + rebuild paperwork (esp. past 80k km) — rebuild receipt is the durability paper trail.
- Low mileage + documented Mazda service — cult collector asset documentation.
What to watch
- Rotary 13B apex-seal wear — loses compression and needs a full specialist rebuild — apex seal wear catastrophic.
- A history of hard cold starts or low compression — pre-failure rotary signs — pre-failure rotary symptoms.
