Should I check the MOT history before buying a 2005 Mercedes Cls 350 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 2005 Mercedes Cls 350 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.

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 2005 Mercedes Cls 350 Auto?

This 2005 Mercedes CLS 350 is in serious trouble: only 4.5% pass MOT first time against the UK average of 80%, and petrol versions don't pass at all, suggesting systemic issues with this model at this age. No vehicles in this cohort have recorded dangerous defects, which is the only bright spot, but the reliability picture is extremely poor.

At an average mileage of 84,360 miles for a 19-year-old car, these are genuinely low-mileage examples, yet they're still failing repeatedly—this isn't wear-and-tear, it's design or maintenance problems. Before considering one, get a pre-purchase inspection focused on the specific failure patterns affecting this generation, and factor in that you'll likely need significant work done immediately after purchase.
