2020 Smart Eq Forfour Prime Exclusive

CarHunch analysed 329 real MOT records for the 2020 Smart Eq Forfour Prime Exclusive. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.

The 2020 SMART EQ ForFour Prime Exclusive passes its MOT first time in 84.8% of cases, which is solidly above the UK average of 80%—a good sign for reliability. The 8.5% dangerous defect rate is low enough not to be a concern, suggesting this electric city car is genuinely safe in practice.

At just 13,240 miles median, these vehicles are still relatively young and lightly used, which explains the clean MOT record. The average of only 0.33 failures and 1.6 advisories per test means routine maintenance is straightforward—focus on tyre condition and brake pad wear when shopping, since electric cars are light on both.

What to check before buying a 2020 Smart Eq Forfour Prime Exclusive

Practical pre-purchase checks for this age and model.

  • 📋 Check the full MOT history. Look for recurring advisories — slow-building issues like corrosion or brake wear patterns show up years before they become failures. Enter the reg below for a full AI analysis.
  • 🔍 Inspect for corrosion in person. Brake pipes, sills, subframes, and chassis legs. Surface rust is normal at this age; structural rust is a serious problem that's expensive to fix and can fail an MOT.
  • 🛞 Check tyres and brakes. The most common advisory items at this age. Budget for replacement if they're near the limit — factor this into your offer price.
  • 📄 Run an HPI check. The MOT history won't show outstanding finance, insurance write-offs, or stolen status — an HPI check will.
