Should I check the MOT history before buying a 2007 Mercedes Benz 320?

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.

The 2007 Mercedes-Benz 320 diesel passes its MOT slightly above the UK average at 82.2%, which is respectable, but nearly four in ten of these cars have recorded a dangerous defect at some point—a notably high proportion that warrants a thorough pre-purchase inspection. The typical example has covered around 93,000 miles and averages 2.85 failures per test, suggesting these aren't bulletproof cars despite their premium badge.

With 17.4 advisories per vehicle on average, wear and tear accumulates across multiple systems rather than clustering in one problem area. Before committing to a purchase, have an independent Mercedes specialist conduct a diagnostic scan and closely inspect the suspension, cooling system, and transmission—the scattered advisory pattern indicates these are common weak points on the aging platform.

We have limited data for the 2007 Mercedes Benz 320 — treat the figures below as indicative rather than definitive.

⚠️ Over 1 in 5 of these vehicles have had a dangerous MOT failure at some point — usually tyres or brakes, and often a one-off issue rather than a persistent problem. The group stats won't tell you which one you're looking at.
