CarHunch analysed 136 real MOT records for the 2021 Mercedes Benz E 300 Amg Line Premium MHEV A. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
The 2021 Mercedes-Benz E 300 AMG Line Premium MHEV performs slightly above the UK average with an 83.6% first-time pass rate, and the 11% dangerous defect rate is reassuringly low—well below the threshold that would concern buyers. The hybrid powertrain shows consistent reliability across the small sample of petrol-electric variants tested.
At 28,067 miles average for a three-year-old car, these vehicles are running well within typical mileage expectations, which partly explains the strong pass rate. With only 0.25 failures per vehicle and 1.3 advisories on average, owners face minimal surprise repair bills—though if you're considering one, a pre-purchase inspection should still flag any brake or suspension wear common to executive saloons.
What to check before buying a 2021 Mercedes Benz E 300 Amg Line Premium MHEV A
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.
