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.
