Does high mileage mean more MG ZR MOT failures at the same age?

At ages 15+, 22.9% of MG ZRs with under 40,000 miles failed first time, against 44.4% of those with over 140,000 miles (2024, n = 305). Inside this age group, higher mileage goes with more failures.

MG ZR MOT: quick answers

What is the MG ZR first-time MOT pass rate?

64.0% of first attempts passed in 2024 (1,988 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 1,988 primary tests: 35.97% failed first time and 70.2% passed when cars fixed at the test centre (PRS) count as passes. The age-adjusted MOT Risk Index 86.5 is shown separately.
