Should I check the MOT history before buying a 2000 Mercedes S320 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 2000 Mercedes S320 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 2000 Mercedes S320 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 2000 Mercedes S320 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.

2000 Mercedes S320 Auto

CarHunch analysed 123 real MOT records for the 2000 Mercedes S320 Auto. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.

This 2000 Mercedes S320 has a catastrophic 4.5% first-time pass rate—nearly 19 times worse than the UK average of 80%—meaning almost every example that enters the MOT bay fails on its first attempt. With zero dangerous defects recorded and virtually no advisories (0.04 failures per vehicle on average), the failures appear to be minor or easily correctable rather than safety-critical issues.

At 115,617 miles average, these cars are well-used but not excessively worn for their age, suggesting the failure pattern isn't simply down to decay. Before buying one, get a pre-purchase inspection from a Mercedes specialist to identify what's failing repeatedly—likely trim, emissions, or electrical items that older luxury cars are prone to—so you know what remedial work to budget for immediately.
