Should I check the MOT history before buying a 2021 Porsche Taycan 4s 79kwh?

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 Taycan 4s 79kwh?

Based on MOT data from 287 vehicles, the 2021 Porsche Taycan 4s 79kwh has a first-time MOT pass rate of 94.4%, 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 Taycan 4s 79kwh?

The 2021 Porsche Taycan 4S is a solid performer on the MOT bench, with an 87.8% first-time pass rate that sits comfortably above the UK average of 80%, and only 9.1% of vehicles have ever recorded a dangerous defect—well within acceptable limits for a buyer considering one. This electric sports saloon demonstrates genuine reliability credentials in its first few years on the road.

At a median mileage of 25,641 miles for a three-year-old car, these Taycans are running well within normal expectations, and the average of just 0.16 failures per vehicle confirms they're not throwing up structural problems. The 1.2 advisories per car suggests minor wear items (brake pads, cabin filters) rather than alarm bells—so before committing to a used example, get a pre-purchase inspection focused on battery health and the electric drivetrain, since MOT data won't catch degradation there.
