This 2022 C 300 AMG Line diesel hybrid passes its MOT first time in 87.8% of cases, meaningfully ahead of the UK average of 80%, which suggests these cars are holding up well mechanically. The dangerous defect rate of 5.5% is reassuringly low and well below concern territory, so safety issues are rare in this cohort.

With advisories averaging 0.5 per vehicle, you're unlikely to face surprise repair bills, though any prospective buyer should still request a full service history and have a pre-purchase inspection done to confirm engine and gearbox condition.

What to check before buying a 2022 Mercedes Benz C 300 Amg Line Prem + D 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.
