What does a Mercedes-Benz GLA cost to run in a fleet?

Of every 100 Mercedes-Benz GLAs tested at age 5, about 13 failed the MOT first time; at age 10, about 20. These are one-year rates for different cars tested in the same year, not a fleet followed over time; the steepest one-year step in this cross-section is between cars aged 4 and 5, 3.54 percentage points (2024).

Mercedes-Benz GLA MOT: quick answers

What is the Mercedes-Benz GLA first-time MOT pass rate?

84.9% of first attempts passed in 2024 (87,343 tests). Retests after repair are excluded; cars fixed at the test centre (PRS) are shown separately.

Why does this number differ from other sites?

Other sites may count retests or all attempts. This page uses 87,343 primary tests: 15.07% failed first time and 87.4% passed when cars fixed at the test centre (PRS) count as passes. The age-adjusted MOT Risk Index 81.3 is shown separately.
