Should I check the MOT history before buying a 2011 Mercedes Benz S350 Bluetec B Fcy L CDI 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 2011 Mercedes Benz S350 Bluetec B Fcy L CDI 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 2011 Mercedes Benz S350 Bluetec B Fcy L CDI 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.

Do I need an HPI check when buying a 2011 Mercedes Benz S350 Bluetec B Fcy L CDI 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 2011 S350 BlueTec is a serious reliability concern: just 8% pass their MOT first time, compared to the UK average of 80%. The median mileage sits at 114,369 miles for a 13-year-old car, which is typical for age, but the real problem is that these engines are simply expensive to keep roadworthy—you're looking at frequent visits to the garage for repairs rather than advisory work.

At 0.19 failures per vehicle on average, this diesel S-Class demands a full pre-purchase inspection by a Mercedes specialist and a frank conversation with your mechanic about upcoming costs. If you're not prepared to budget £1,500–£3,000 annually for maintenance and repairs on a high-mileage luxury diesel, walk away.
