2018 Mercedes Benz Glc 220 D 4matic Amg Line Auto
CarHunch analysed 403 real MOT records for the 2018 Mercedes Benz Glc 220 D 4matic Amg Line Auto. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
This 2018 GLC 220 D has a first-time MOT pass rate of just 48.5%, nearly 32 percentage points below the UK average of 80%, which is a significant red flag for reliability. The good news is that dangerous defects are essentially absent (0%), so when these cars do fail, it's not typically a safety issue.
At 56,226 miles median, these vehicles are averaging reasonable mileage for their age, yet they're still generating substantial MOT failures—0.07 per vehicle on average suggests recurring niggles rather than catastrophic breakdowns. If you're considering this model, budget for an independent pre-purchase inspection by a Mercedes specialist, as the MOT history suggests these cars need closer attention than most six-year-olds.
What to check before buying a 2018 Mercedes Benz Glc 220 D 4matic 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.
