Should I check the MOT history before buying a 2021 Porsche Cayman?

Yes. Look for recurring advisories — slow-building issues like corrosion or brake wear patterns show up years before they become failures. A full MOT history analysis will highlight patterns that a single test result won't reveal.

Check brake pipes, sills, subframes, and chassis legs. Surface rust is normal at this age; structural rust is a serious problem that is expensive to fix and can fail an MOT.

Tyres and brakes are the most common advisory items on vehicles of this age. Budget for replacement if they are near the limit, and factor this into your offer price.

Moderate sample. 478 vehicles on record. Figures are indicative — the specific vehicle's history matters more than these averages.

The 2021 Porsche Cayman is significantly more reliable than the UK average, with a 94.4% first-time pass rate compared to 80%—this is a genuinely strong result that suggests well-built cars or exceptionally diligent owners. Dangerous defects are rare at just 2.9%, so safety concerns aren't a buyer worry with this cohort.

These Caymans are running very light mileage for their age at a median of 14,056 miles, which explains both the high pass rate and the minimal failure rate of 0.08 per vehicle. The 0.7 advisories per car indicate minor wear rather than serious issues, but check the service history carefully when buying—low mileage can mask deferred maintenance, so verify that scheduled work has actually been done.

The 2021 Porsche Cayman passes its MOT first time more often than most UK vehicles (97.2% vs ~80% average) — and when it does fail, it's usually something minor and cheap to fix.
