Mercedes Benz E 300 Amg Line Premium + Auto (2018)
2018 Mercedes Benz E 300 Amg Line Premium + Auto
CarHunch analysed 132 real MOT records for the 2018 Mercedes Benz E 300 Amg Line Premium + Auto. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
This 2018 E 300 is a serious red flag: just 4.5% pass first time against the UK average of 80%, meaning 95 out of 132 examples failed their MOT on first attempt. The petrol models showed a 0% first-time pass rate across 126 vehicles, suggesting systemic issues rather than isolated problems—yet crucially, there were zero dangerous defects recorded and zero average failures or advisories per vehicle, which is a puzzling contradiction that warrants investigation into what's actually failing these cars.
With an average mileage of 32,172 miles for a 2018 model, these are relatively low-mileage examples, so the failures aren't wear-related. Before buying one, get an independent pre-purchase inspection to identify what specific components are repeatedly tripping the MOT, because the raw pass/fail numbers don't align with the fault detail—this could indicate a data issue or a very specific defect affecting the test protocol rather than vehicle safety.
What to check before buying a 2018 Mercedes Benz E 300 Amg Line Premium + Auto
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.
