Should I check the MOT history before buying a 2004 Mercedes E270 CDI Avantgarde Auto?

Yes. Look for recurring advisories — slow-building issues like corrosion or brake wear patterns show up years before they become failures. A full MOT history analysis will highlight patterns that a single test result won't reveal.

What corrosion should I look for when inspecting a 2004 Mercedes E270 CDI Avantgarde Auto?

Check brake pipes, sills, subframes, and chassis legs. Surface rust is normal at this age; structural rust is a serious problem that is expensive to fix and can fail an MOT.

How are tyres and brakes typically on a 2004 Mercedes E270 CDI Avantgarde Auto?

Tyres and brakes are the most common advisory items on vehicles of this age. Budget for replacement if they are near the limit, and factor this into your offer price.

Based on MOT data from 124 vehicles, the 2004 Mercedes E270 CDI Avantgarde Auto has a first-time MOT pass rate of 70.9%, indicating generally reliable for its class. Always check the full MOT history of any specific vehicle before buying.

Do I need an HPI check when buying a 2004 Mercedes E270 CDI Avantgarde Auto?

Yes. The MOT history will not show outstanding finance, insurance write-offs, or stolen status. An HPI check covers these areas and should be part of any used car purchase.

This 2004 Mercedes E270 CDI has a first-time MOT pass rate of just 33.2%, well below the UK average of 80%, which is a serious red flag for reliability. The good news is that dangerous defects are absent from this cohort, but the consistently poor pass rate means you're looking at a car that will likely need welding, suspension, or emissions work before it clears its test.

At 154,557 miles on average, these cars have been well-used, and the 0.73 failures per vehicle tells you that problems tend to be multiple rather than isolated—when one thing fails, others usually need attention too. If you're considering this model, budget for a pre-purchase inspection by a Mercedes specialist and expect remedial work before registration; these aren't cars to buy at auction and hope for the best.
