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

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 RS Cosworth?

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 RS Cosworth?

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 Ford Sierra RS Cosworth?

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.

No MOT data — worth knowing

Got a specific Ford Sierra RS Cosworth you're checking out?

The real detail is in the individual vehicle report — MOT history, AI Hunches, mileage timeline, and defect patterns for that specific reg.

This cohort has no MOT test data in the DVLA light-vehicle database, so we cannot provide a reliability verdict based on actual test results. The 1988 Ford Sierra RS Cosworth is a 35-year-old performance icon — a turbocharged saloon that was built for speed, not longevity, and most survivors today are either cherished classics in specialist hands or have been heavily modified. If you're considering one, your priority should be mechanical history and provenance rather than MOT pass rates; have a pre-purchase inspection by a Cosworth specialist, verify engine authenticity, and check for rust and turbo wear. These cars demand enthusiast ownership and deep pockets for maintenance — they're not everyday transport.

MOT statistics not available

We have 1,557 1988 Ford Sierra RS Cosworth vehicles on record, but none have light-vehicle MOT history in our data source.

There are a few reasons this can happen:

Heavy commercial vehicle — trucks, buses and coaches over 3.5 tonnes are tested under the DVSA annual HGV/PSV regime, which uses a separate database not included in our data source
Imported vehicles — vehicles registered abroad and recently brought to the UK may have no UK MOT history yet
MOT-exempt — vehicles manufactured before 1986 qualify under the 40-year rolling exemption; some specialist and agricultural vehicles are also exempt
Never used on public roads — some vehicles are registered but kept off-road and have never required an MOT
