Should I check the MOT history before buying a 1988 Mercedes 300 SE 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 1988 Mercedes 300 SE 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 1988 Mercedes 300 SE 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 1988 Mercedes 300 SE 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.

1988 Mercedes 300 SE Auto

CarHunch analysed 910 real MOT records for the 1988 Mercedes 300 SE Auto. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.

This 1988 Mercedes 300 SE Auto is a reliability disaster by MOT standards—just 10% pass first time compared to the UK average of 80%, and the petrol version shows a 0% pass rate across 905 vehicles tested. There are no recorded dangerous defects in this cohort, but that's the only silver lining in an otherwise dire picture.

At an average mileage of 154,319 miles for a 36-year-old car, these vehicles are heavily worn, and the complete absence of recorded failures and advisories in the data suggests these cars either aren't being properly tested or the dataset is incomplete—which itself should raise red flags about data quality or vehicle condition. If you're seriously considering one of these, have a pre-purchase inspection by a Mercedes specialist, because relying on MOT history alone won't protect you.
