Should I check the MOT history before buying a 1999 BMW 840?

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.

The 1999 BMW 840 passes its MOT at 78.1%, slightly below the UK average of 80%, and critically, 22.1% of these cars have recorded a dangerous defect at some point—a real buyer concern that suggests you need a thorough pre-purchase inspection. These are aging luxury saloons with modest mileage for their age (median 80,782 miles), yet they rack up an average of 4.08 failures and 26.6 advisories per test, pointing to expensive wear on complex German engineering.

The high advisory count is the story here: this isn't a car failing on major items every test, but rather accumulating niggles across suspension, electrics, and trim that cost money to fix. Before you buy one, get a pre-purchase inspection from a BMW-specialist mechanic, not a general garage, and budget for the advisories that will likely appear at the next MOT.
