Bentley Mulsanne (2015)
2015 Bentley Mulsanne
CarHunch analysed 118 real MOT records for the 2015 Bentley Mulsanne. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
The 2015 Bentley Mulsanne passes its MOT on the first attempt 94.5% of the time—well above the UK average of 80%—and only 9.3% of cars in this cohort have ever recorded a dangerous defect, which is reassuring for a luxury purchase. This is a genuinely reliable car by MOT standards, with fewer than one failure per vehicle on average.
These Mulsannes are running low mileage for their age (median 21,325 miles), which partly explains the clean record, though the 2.7 advisories per car suggest minor wear is starting to show on electrical and trim components. If you're considering one, have a pre-purchase inspection focus on the air suspension and electronic gearbox—the luxury systems that tend to be expensive when they go wrong.
What to check before buying a 2015 Bentley Mulsanne
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.
