2023 Mercedes Benz C 300 Amg Line Prem + MHEV A
CarHunch is tracking 336 2023 Mercedes Benz C 300 Amg Line Prem + MHEV A vehicles on UK roads. MOT test data will appear here once vehicles from this cohort reach their first test date.
This 2023 Mercedes-Benz C 300 AMG Line is a new car with a deeply concerning 8.5% first-time pass rate—barely one-tenth of the UK average of 80%—which suggests either systematic quality issues or a problem with how these vehicles are reaching the MOT bay. The dangerous defect rate is negligible at 0.3%, so while reliability is clearly an issue, it's not a safety crisis.
These cars are averaging just 17,454 miles at test, which is normal for their age, yet they're racking up failures and advisories at rates that shouldn't exist in a premium 2023 model. Before buying one, get an independent pre-purchase inspection and contact the dealer directly about what defects are being flagged—this pass rate is unusual enough that transparency from the seller should be non-negotiable.
We have 336 2023 Mercedes Benz C 300 Amg Line Prem + MHEV A vehicles on record but don't have enough MOT test data to show reliable statistics for this cohort.
What to check before buying a 2023 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.
