CarHunch analysed 122 real MOT records for the 2021 Mercedes Benz Amg C 63 S Night Ed Prem + A. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.

This 2021 AMG C 63 S is notably reliable, with a 90.2% first-time pass rate that sits 10 points above the UK average—a strong showing for a high-performance Mercedes. The 17.2% rate of dangerous defects is worth noting for a buyer, though not alarming, and suggests keeping up with scheduled maintenance to stay ahead of potential brake or suspension issues.

At just over 21,500 miles median, these cars are running low for their age, which partly explains the healthy pass rate and minimal failure burden of 0.28 per vehicle. The 1.3 advisories per car point to minor wear items rather than systemic problems—a clean pre-purchase inspection focusing on the turbocharged engine bay and gearbox health will give you confidence in what's typically a solid used buy.

What to check before buying a 2021 Mercedes Benz Amg C 63 S Night Ed Prem + 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.
