In the Netherlands, 54.7% of Lancia Deltas failed their periodic roadworthiness inspection, against 50.8% for all cars there (2024 by country, n = 1,321 inspections).
Both readings are shown: this comparison changes when usage or inspection rules differ.
Inspections abroad disagree: none point the same way as Britain, the Netherlands do not. Test rules, climate and how the vehicles are used differ, so both readings are shown.

How the MOT Risk Index and every figure on this page are calculated: methodology.
What is wrong on this page? One tap sends the category only, no text and nothing about you.
87.3% of first attempts passed in 2024 (534 tests). Retests after repair are excluded; cars fixed at the test centre (PRS) are shown separately.
Other sites may count retests or all attempts. This page uses 534 primary tests: 12.73% failed first time and 89.9% passed when cars fixed at the test centre (PRS) count as passes. The age-adjusted MOT Risk Index 32.7 is shown separately.
