2018 Mercedes Benz A 180 Sport D Auto
CarHunch analysed 114 real MOT records for the 2018 Mercedes Benz A 180 Sport D Auto. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
This 2018 Mercedes-Benz A 180 Sport D Auto has a first-time MOT pass rate of 64.1%, which is notably below the UK average of 80%, suggesting reliability concerns relative to its peers. The good news is that none of the 114 vehicles analysed registered a dangerous defect, so structural and safety failures aren't the issue here.
With median mileage of 45,564 miles for a six-year-old car, these examples are running slightly below typical wear, yet still failing MOTs at a higher-than-average rate—pointing to component or system vulnerabilities rather than abuse. The minimal failure count (0.09 per vehicle) and zero advisories indicate that when this car does fail, it's usually one specific problem rather than cumulative decay, so if you're considering one, prioritise a pre-purchase inspection focusing on the common failure points that aren't yet showing up in this data.
What to check before buying a 2018 Mercedes Benz A 180 Sport D 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.
