2003 Mercedes E270 CDI Avantgarde Auto

CarHunch analysed 100 real MOT records for the 2003 Mercedes E270 CDI Avantgarde Auto. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.

This 2003 Mercedes E270 CDI is a genuinely unreliable proposition at MOT time: just 27% pass first time versus the UK average of 80%, and nearly half of these vehicles rack up an average of 0.49 failures per test. While dangerous defects aren't prevalent at 0%, the sheer failure rate makes this a high-maintenance buy that will demand regular and costly repairs.

At 155,000 miles median mileage these cars have done proper miles for their age, and the complete absence of advisories suggests failures tend to be serious rather than minor wear items. If you're considering one, budget for immediate pre-purchase inspection by a Mercedes specialist, because this cohort simply doesn't pass first time—expect significant work before you even own it.

What to check before buying a 2003 Mercedes E270 CDI Avantgarde Auto

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.
