Should I check the MOT history before buying a 1988 Mercedes 420 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 420 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 420 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 420 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.

No MOT data — worth knowing

Got a specific Mercedes 420 SE Auto 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.

There is no MOT test data available for the 1988 Mercedes 420 SE in the DVLA light-vehicle database, so we cannot provide a reliability verdict based on pass rates or defect patterns. This 1980s luxury saloon is now 35+ years old, and the 197 vehicles analysed carry an average mileage of 156,913 miles—typical for surviving examples of this age that are usually kept as classics or cherished family heirlooms rather than everyday drivers.

Any 1988 Mercedes of this calibre that has made it to the MOT test bench today is likely to be well-maintained by an enthusiast owner, not a high-mileage workhorse. If you're considering one, focus on service history, rust inspection (especially in the floor and sills), and the condition of its cooling system and fuel injectors—common weak points on W124-generation Mercedes—rather than relying on MOT statistics that simply don't exist for this cohort.

MOT statistics not available

We have 197 1988 Mercedes 420 SE Auto 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
