Mercedes Benz Slc (2019)
2019 Mercedes Benz Slc
CarHunch analysed 992 real MOT records for the 2019 Mercedes Benz Slc. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
The 2019 Mercedes-Benz SLC is a notably reliable performer, with a 93.4% first-time MOT pass rate that sits well above the UK average of 80%, though 14.5% of vehicles have recorded at least one dangerous defect across their testing history—worth verifying during a pre-purchase inspection. These cars are running very low mileage for their age (median just 17,030 miles), suggesting they're typically garage-kept or lightly driven, which aligns with the low failure rate of 0.35 per vehicle.
When failures do occur, they tend to be minor: advisories average 2.7 per car, indicating wear items rather than structural problems. Before committing to a purchase, get an independent pre-purchase inspection focused on the cooling system and convertible roof mechanism, as these are common weak points on SLCs and won't always show up in MOT records.
What to check before buying a 2019 Mercedes Benz Slc
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.
