Should I check the MOT history before buying a 2021 Smart Eq Forfour Exclusive?

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 Smart Eq Forfour Exclusive?

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 Smart Eq Forfour Exclusive?

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.

Is the 2021 Smart Eq Forfour Exclusive reliable?

Based on MOT data from 210 vehicles, the 2021 Smart Eq Forfour Exclusive has a first-time MOT pass rate of 89.8%, 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 Smart Eq Forfour Exclusive?

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.

The 2021 Smart EQ Forfour Exclusive passes its MOT on the first attempt 85.1% of the time, which is a solid 5 percentage points above the UK average and suggests good baseline reliability for this electric city car. The dangerous defect rate sits at just 7.6%, well below the concerning threshold, so safety isn't a red flag here.

These vehicles are running relatively low mileage—a median of 12,735 miles—which is typical for compact EVs used mainly in urban driving, and the minimal failure rate (0.3 per vehicle) reflects this light usage pattern. When you do take one to test, expect around one advisory per car on average, likely minor trim or wear items; focus your inspection on the battery health and charging system rather than mechanical engine wear.

We have limited data for the 2021 Smart Eq Forfour Exclusive — treat the figures below as indicative rather than definitive.

⚠️ Around 1 in 20 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.
