2021 Mercedes Benz Amg Cla 35 Premium + 4matic A
CarHunch analysed 157 real MOT records for the 2021 Mercedes Benz Amg Cla 35 Premium + 4matic A. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
This 2021 Mercedes-AMG CLA 35 posts a first-time pass rate of 81.2%, marginally above the UK average of 80%, suggesting broadly typical reliability for a performance compact saloon. However, 16.6% of these cars have recorded a dangerous defect at some point—notably higher than the typical threshold—so a pre-purchase inspection by a Mercedes specialist is essential.
At just over 26,600 miles median, these vehicles are relatively low-mileage for their age, yet they're already averaging 0.35 failures and 1.3 advisories per test, indicating early wear issues common to turbocharged performance models. Budget for regular brake and suspension checks, and always review the full MOT history before committing to purchase.
What to check before buying a 2021 Mercedes Benz Amg Cla 35 Premium + 4matic 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.
