Car Manufacturer
Customer Experience Index
The Car Manufacturer Customer Experience Index is built from almost a quarter of a million recent customer reviews, analysed through a composite model that blends verified star ratings with sensitivity‑weighted diagnostics.
To reflect the structure of the UK market, manufacturers are grouped into three segments — Luxury & Performance, Premium, and Mainstream — with each brand ranked according to its composite score within its segment.
The Index provides a clear, data‑driven view of how consistently each OEM delivers customer experience across its retail network, highlighting meaningful differences in performance without commentary or interpretation, and the rankings below present the latest results for all three segments.
