2021 Mercedes Benz Amg A 35 Premium + 4matic Ed A

CarHunch analysed 192 real MOT records for the 2021 Mercedes Benz Amg A 35 Premium + 4matic Ed A. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.

This AMG A 35 is a strong performer with a 91.2% first-time pass rate, well above the UK average of 80%, and only 18.2% of vehicles have ever recorded a dangerous defect—a manageable level for a high-performance model. The low failure rate of 0.25 per vehicle suggests mechanically sound cars once they're running, though the 1.4 advisories per vehicle signal minor maintenance items emerging as they age.

At just under 25,000 miles average, these 2021 cars are still relatively young with moderate mileage, so you're buying into a vehicle early in its lifecycle where the reliability picture is still settling. Check the full MOT history of any used example for the pattern of those advisories—if they're clustering around the same systems (suspension, brakes, electrics), that's a red flag worth investigating before purchase.

What to check before buying a 2021 Mercedes Benz Amg A 35 Premium + 4matic Ed 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.
