Mercedes Benz C (2019)
2019 Mercedes Benz C
CarHunch analysed 24,386 real MOT records for the 2019 Mercedes Benz C. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
The 2019 Mercedes-Benz C is a strong performer, passing its MOT first time in 90.7% of cases—well above the UK average of 80%—though nearly a quarter of these cars (22.4%) have recorded a dangerous defect at some point, which is worth factoring into your inspection checklist. Petrol versions edge out diesels with a 91.3% pass rate versus 89.9%, suggesting marginally better reliability on the petrol side.
At a median mileage of 30,739 miles for a five-year-old car, these vehicles are running relatively lightly, and the low average failure rate of 0.51 per car reflects their generally sound condition. The 3.6 advisories per vehicle are typical wear-and-tear items; before you buy, request the full MOT history and specifically check for any previous dangerous defects or repeated advisory trends around suspension or electrical systems.
What to check before buying a 2019 Mercedes Benz C
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.
- ⚠️ 22.4% of these vehicles have had a dangerous defect recorded. Enter the reg below — the full MOT history will show exactly what was flagged and whether it was resolved.
- 📄 Run an HPI check. The MOT history won't show outstanding finance, insurance write-offs, or stolen status — an HPI check will.
