Of every 100 Porsche Boxsters tested at age 5, about 4 failed the MOT first time (rough estimate); at age 10, about 8 (rough estimate). These are one-year rates for different cars tested in the same year, not a fleet followed over time (2024).

Porsche Boxster MOT: quick answers

What is the Porsche Boxster first-time MOT pass rate?

82.4% of first attempts passed in 2024 (32,363 tests). Retests after repair are excluded; cars fixed at the test centre (PRS) are shown separately.
