Does an MG 3 rust more than average?

Allowing for age, MG 3 MOTs record corrosion failures at 2.5 times the national rate: 1.88% of tests against 0.77% (2024 + geographic layers, n = 21,053).

What do six years of MOTs show about owning an MG 3?

Of failed MG 3 MOTs, 46.2% were retested the same day and a further 50.1% within 10 days; the median failed car passed its retest after 1 day (2019–2024, n = 12,704).

MG 3s aged 5 to 9 doing under 5,000 miles a year failed first time in 17.4% of tests, against 34.1% for those doing 8,000 to 12,000 miles (2019–2024, n = 20,711).

How many years is an MG 3 likely to last?

MG 3s aged 10 are forecast to keep taking MOTs for at least 0.5 more years; the survival curve is observed only until age 10, so the true figure is likely higher.

If an MG 3 fails, does it fail again?

27.2% of MG 3s that failed an MOT failed the next one too, against 20.7% after a pass (2019–2024, n = 4,674). The failure most likely to come back is ‘body, chassis, structure’: 31.0% of those fails recurred at the next MOT.

What does an MG 3 cost to run in a fleet?

Of every 100 MG 3s tested at age 5, about 19 failed the MOT first time; at age 10, about 32 (rough estimate). 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 8 and 9, 5.13 percentage points (2024).

MG 3 MOT: quick answers

What is the MG 3 first-time MOT pass rate?

76.0% of first attempts passed in 2024 (21,060 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 21,060 primary tests: 24% failed first time and 81.5% passed when cars fixed at the test centre (PRS) count as passes. The age-adjusted MOT Risk Index 124.6 is shown separately.
