Should I check the MOT history before buying a 2020 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 2020 Porsche Taycan 4s 79kwh?

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 2020 Porsche Taycan 4s 79kwh?

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 449 vehicles, the 2020 Porsche Taycan 4s 79kwh has a first-time MOT pass rate of 93.1%, 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 2020 Porsche Taycan 4s 79kwh?

Yes. The MOT history will not show outstanding finance, insurance write-offs, or stolen status. An HPI check covers these areas and should be part of any used car purchase.

Moderate sample. 449 vehicles on record. Figures are indicative — the specific vehicle's history matters more than these averages.

The 2020 Porsche Taycan 4S is passing its MOTs at 84.2%, which beats the UK average of 80% and suggests solid build quality for an electric performance car. However, one in ten of these vehicles (10.5%) has recorded a dangerous defect at some point, so mechanical inspection before purchase is essential—this is a complex machine.

With a median mileage of just over 25,900 miles for a four-year-old car, these Taycans are running light, which partly explains the healthy pass rate and low failure average of 0.23 per vehicle. The 1.4 advisories per car suggest minor wear items cropping up, but before committing, get a full diagnostic report on the battery health and cooling system—electrical complexity is where early problems often hide on EVs.

The 2020 Porsche Taycan 4s 79kwh passes its MOT first time more often than most UK vehicles (93.1% vs ~80% average) — and when it does fail, it's usually something minor and cheap to fix.

⚠️ About 1 in 12 of these vehicles have had a dangerous MOT failure at some point — usually tyres or brakes, and often a one-off issue rather than a persistent problem. The group stats won't tell you which one you're looking at.

For context

✅ Good baseline reliability. A 93.1% first-time pass rate puts this well above the UK average — it's a well-sorted vehicle in this age bracket.

🔍 The dangerous defect figure is real. Most are one-off tyre failures or brake issues — not structural problems. But it's exactly why checking the individual vehicle's history is essential, not optional.

These stats describe 449 vehicles as a group. The specific vehicle you're looking at could be the one good example or the one outlier. Run its registration to find out.
