2022 Mercedes Benz C 300 Amg Line Prem + MHEV A

CarHunch analysed 294 real MOT records for the 2022 Mercedes Benz C 300 Amg Line Prem + MHEV A. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.

This C 300 AMG Line is performing well above the UK average with an 89.1% first-time pass rate, well ahead of the typical 80%, which signals strong build quality and reliability in its early years. The dangerous defect rate sits at 5.4%, below concerning levels, so safety isn't a red flag here.

At just under 22,000 miles on average for a 2022 model, these cars are running low mileage, which explains the minimal failure rate of 0.12 per vehicle—you're looking at a very young, well-maintained cohort. The modest advisory count of 0.5 per vehicle suggests minor wear items are starting to appear, but nothing systematic; when shopping for one, focus your inspection on the hybrid battery warranty status and whether service history is complete, as gaps could mask underlying electrical issues common to high-tech Mercedes.

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