Mileage and MOT
MOT, from the government's MOT records (DVSA, the Driver and Vehicle Standards Agency), as of 10 November 2026: valid until 2 June 2027.
It failed its MOT on 30 May 2026 (offside front tyre has a cut in excess of the requirements deep enough to reach the ply or cords; nearside rear hydraulic brake calliper leaking) and passed 4 days later, on 3 June 2026.
There were no advisories at the latest test.
Mileage at that test: 69,098 miles. The advert says 13,000 miles, fewer than the MOT record, so ask the dealer which is right.
Advertised mileage is about 8,000 miles lower than the median mileage of a 2021 Porsche 718 Cayman on AskCar.
