CarHunch analysed 109 real MOT records for the 2020 Mercedes Benz Amg Glc 63 S Premium 4m + A. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
This 2020 AMG GLC 63 S is substantially more reliable than the typical UK car, with a 92.9% first-time pass rate against the 80% average—and only 6.4% have ever suffered a dangerous defect, which is reassuringly low. You're looking at a well-engineered performance SUV that passes its MOTs with consistent confidence.
At 30,794 miles average, these cars are running predictably for their age and haven't been thrashed. The 0.23 average failures per vehicle confirms that when something does break, it's rare, though the 1.7 advisories per car suggest you should budget for minor maintenance—typical for a high-spec AMG model with complex electronics. Before buying, request the full MOT history to check what those advisories have been, as preventative work on an AMG is far cheaper than reactive repairs.
What to check before buying a 2020 Mercedes Benz Amg Glc 63 S Premium 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.
