Should I check the MOT history before buying a 1988 Ford Sierra?

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 Ford Sierra?

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 Ford Sierra?

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.

Is the 1988 Ford Sierra reliable?

Based on MOT data from 4,425 vehicles, the 1988 Ford Sierra has a first-time MOT pass rate of 67.6%, indicating average reliability for its class. Always check the full MOT history of any specific vehicle before buying.

Do I need an HPI check when buying a 1988 Ford Sierra?

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.

The 1988 Ford Sierra passes its MOT first time in just 67.6% of cases, well below the UK average of 80%, so expect a meaningful failure rate if you're buying one of these cars. The good news is that dangerous defects are relatively uncommon at 7%, though the low median mileage of just over 50,000 miles suggests many of these vehicles are genuinely elderly and may have been driven sparingly rather than well-maintained.

When these Sierras do fail, it's typically for multiple reasons—owners face an average of 1.04 failures and 3.0 advisories per test, indicating a cumulative wear issue rather than single-point failures. Before buying, get a full pre-purchase inspection focused on rust, electrics, and brake components, and factor in that you'll likely need remedial work before it passes its next MOT.

The 1988 Ford Sierra has a below-average first-time pass rate (67.6% vs ~80% UK average) — check the specific vehicle's full MOT history carefully before buying.

⚠️ Around 1 in 20 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.

For context

⚠️ Below average. More vehicles in this cohort fail their first MOT than typical. Scrutinise this vehicle's history — look for recurring issues, not just the latest result.

🔧 Expect consumable spend. An average of 3 advisories per vehicle tells you wear items (tyres, brakes) get flagged regularly. Budget for them — they're not surprises.

🔍 The dangerous defect figure is real. Most are one-off tyre failures or brake issues — not structural problems. But it's exactly why checking the individual vehicle's history is essential, not optional.

These stats describe 4,425 vehicles as a group. The specific vehicle you're looking at could be the one good example or the one outlier. Run its registration to find out.
