2014 Bentley Unknown

CarHunch analysed 129 real MOT records for the 2014 Bentley Unknown. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.

This 2014 Bentley has a first-time MOT pass rate of just 8.3%, starkly below the UK average of 80%—a severe reliability red flag that suggests serious structural or mechanical issues plague the vast majority of these vehicles. The complete absence of dangerous defects (0%) is the only saving grace, though it hardly matters when only 1 in 12 cars pass their test without any faults.

With a median mileage of just 22,044 miles for a decade-old car, these Bentleys are either garage queens or have been heavily serviced, yet they still fail MOT in dramatic numbers—indicating design or age-related problems money alone cannot easily fix. If you're considering one, budget for immediate professional pre-purchase inspection and expect significant repair costs whatever the odometer reads.

What to check before buying a 2014 Bentley Unknown

Practical pre-purchase checks for this age and model.

  • 📋 Check the full MOT history. Look for recurring advisories — slow-building issues like corrosion or brake wear patterns show up years before they become failures. Enter the reg below for a full AI analysis.
  • 🔍 Inspect for corrosion in person. Brake pipes, sills, subframes, and chassis legs. Surface rust is normal at this age; structural rust is a serious problem that's expensive to fix and can fail an MOT.
  • 🛞 Check tyres and brakes. The most common advisory items at this age. Budget for replacement if they're near the limit — factor this into your offer price.
  • 📄 Run an HPI check. The MOT history won't show outstanding finance, insurance write-offs, or stolen status — an HPI check will.
