Should I check the MOT history before buying a 2021 Porsche 911 Targa 4s?

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.

What corrosion should I look for when inspecting a 2021 Porsche 911 Targa 4s?

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.

How are tyres and brakes typically on a 2021 Porsche 911 Targa 4s?

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.

Based on MOT data from 355 vehicles, the 2021 Porsche 911 Targa 4s has a first-time MOT pass rate of 97.8%, indicating generally reliable for its class. Always check the full MOT history of any specific vehicle before buying.

Do I need an HPI check when buying a 2021 Porsche 911 Targa 4s?

Moderate sample. 355 vehicles on record. Figures are indicative — the specific vehicle's history matters more than these averages.

The 2021 Porsche 911 Targa 4S passes its MOT first time at 80.5%, virtually identical to the UK average of 80%, with an exceptionally low dangerous defect rate of just 2.2%—well below typical concern levels. This is a reliable car by MOT standards, with petrol models maintaining that 80.2% pass rate consistently.

At under 12,000 miles on average, these cars are lightly used despite being three years old, which explains the minimal failure rate of 0.05 per vehicle and modest advisory count of 0.5. When buying one, focus your inspection on the cooling system and suspension components that occasionally appear as advisories on sports cars of this age, rather than expecting widespread mechanical issues.

The 2021 Porsche 911 Targa 4s passes its MOT first time more often than most UK vehicles (97.8% vs ~80% average) — and when it does fail, it's usually something minor and cheap to fix.
