CarHunch analysed 125 real MOT records for the 2017 Mercedes Benz A 180 D Sport Executive. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.

The 2017 Mercedes-Benz A 180 D Sport Executive posts an 82.2% first-time pass rate, marginally above the UK average of 80%, suggesting broadly reliable condition across this cohort. No vehicles in this sample have ever suffered a dangerous defect, which is reassuring for prospective buyers.

These cars are running at a sensible 68,000 miles on average for a seven-year-old model, and they're barely failing anything—just 0.26 failures per vehicle with zero advisories recorded. When you're shopping for one, ask the seller for full service history and recent MOT printouts to confirm it has avoided any pattern of electrical or fuel system issues, since the near-zero advisory count suggests defects tend to be outright failures rather than emerging problems.

What to check before buying a 2017 Mercedes Benz A 180 D Sport Executive

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.
