CarHunch analysed 304 real MOT records for the 2020 Mercedes Benz Gla 220 Amg Line Prem + D 4m A. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
This 2020 GLA 220 diesel is a strong performer, with a 93.4% first-time pass rate that sits well above the UK average of 80%, and only 5.3% of vehicles ever flagged for dangerous defects—a reassuringly low figure. You're looking at a reliable, well-built compact SUV that buyers are clearly looking after.
At 30,265 miles median and just 0.19 failures per vehicle, these cars are showing minimal structural problems so far. The 2.0 advisories per vehicle suggest routine wear items and minor maintenance rather than systemic issues—if you're considering one, a pre-purchase inspection by an independent Mercedes specialist is still worthwhile, but the overall pattern is genuinely encouraging.
What to check before buying a 2020 Mercedes Benz Gla 220 Amg Line Prem + D 4m A
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.
