MOT, from the government's MOT records (DVSA, the Driver and Vehicle Standards Agency), as of 4 November 2026: valid until 1 June 2027.

It failed its MOT on 29 May 2026 (nearside front brake pad(s) incorrectly mounted friction material lose from backing pad) and passed 4 days later, on 2 June 2026.

Advisories at the latest test: nearside front tyre worn close to legal limit/worn on edge; offside front tyre worn close to legal limit/worn on edge; both rear tyres perishing and getting low on tread.
