About This Data
This analysis uses real MOT test results from the DVSA database, covering 1,598 tests on Smart Fortwo Passion Mhd Auto vehicles between 2000 and 2023.
Year-Adjusted Scoring (v2.1): In year-by-year breakdowns, each vehicle is compared against the national average for vehicles of the same model year. This removes the natural bias where newer cars pass more often, allowing fair comparisons across eras.
Evidence-Tiered Durability: We separate "proven durability" (vehicles tested at 11+ years old) from "early performers" (3-6 years old). Only vehicles with proven long-term data are used for durability claims. Age-band comparisons use weighted national averages.
Minimum thresholds: 100 tests for proven durability rankings, 100 tests for early performer rankings. Pass rates are calculated as first-time passes, excluding retests.
The overall national average MOT pass rate is 71.44% based on 32,300,000 tests across all manufacturers. Year-specific averages range from ~59% (2009 vehicles) to ~88% (2020 vehicles).
