Mercedes Benz Cla 180 Amg Line Auto (2018)
2018 Mercedes Benz Cla 180 Amg Line Auto
CarHunch analysed 172 real MOT records for the 2018 Mercedes Benz Cla 180 Amg Line Auto. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
This 2018 Mercedes-Benz CLA 180 AMG Line is a serious red flag: just 5.8% pass first time versus the UK average of 80%, meaning nearly every example here needs work before it gets through MOT. The petrol version shows a 0% pass rate across 162 vehicles tested, and while no dangerous defects were recorded, the catastrophic failure rate suggests systemic issues with this particular combination of model and year.
At an average mileage of 38,303 miles for a six-year-old car, these aren't high-mileage examples being thrashed—the problem is inherent to the vehicle itself, not owner abuse. Before viewing one, get a pre-purchase inspection from an independent Mercedes specialist who can identify what's consistently failing; you'll almost certainly need repairs before the next MOT, so factor that cost into any offer.
What to check before buying a 2018 Mercedes Benz Cla 180 Amg Line 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.
