2002 Mercedes Benz A Class

CarHunch analysed 15,840 real MOT records for the 2002 Mercedes Benz A Class. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.

The 2002 Mercedes-Benz A-Class has a first-time MOT pass rate of 71.3%, which is notably below the UK average of 80% and signals reliability concerns for a car now over two decades old. More worryingly, nearly one in three of these vehicles (32.9%) have recorded a dangerous defect at some point, making this a real buyer concern—petrol and diesel variants perform similarly poorly at 71.5% and 70.2% respectively.

These cars are running at a median of 63,444 miles, which is relatively low for their age and suggests many examples have been light-use or cherished, yet they still average 4.86 failures and 21 advisories per test. Before committing to one, prioritise a pre-purchase inspection focused on suspension, steering, and brake components, where Mercedes A-Class models of this era commonly fail.

What to check before buying a 2002 Mercedes Benz A Class

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.
  • ⚠️ 32.9% of these vehicles have had a dangerous defect recorded. Enter the reg below — the full MOT history will show exactly what was flagged and whether it was resolved.
  • 📄 Run an HPI check. The MOT history won't show outstanding finance, insurance write-offs, or stolen status — an HPI check will.
