The most recent MOT was on 2023-07-12 — just under three years ago — and it passed with one defect: a minor exhaust gas leak (6.1.2(a)). That’s the only recorded issue in the last two passes. A clear recurring pattern emerges: exhaust leaks and lighting failures. The same minor exhaust leak appeared in both the 2023 pass and the 2022 fail. Lighting faults were severe in 2022 — multiple position lamps, headlamps (dip and main beam), rear plate lamp, and reflector all failed — but completely absent in the two prior passes (2020 and 2019) and the 2023 pass. That suggests the lighting system was repaired or replaced after 2022, and has held up since. The trend is cautiously improving: the 2022 failure was serious but isolated in time, followed by two clean passes (2023 and — by implication — the 2020/2019 run). However, the persistent exhaust leak across two MOTs indicates it hasn’t been fixed, and may be worsening slowly. At 44,284 miles over 35 years, average use is just 1,265 miles per year — well below typical usage. This strongly suggests long periods of storage or very light use.
