What's good
If you’re able to look beyond the looks of the BMW X6, you’ll find an SUV that remains hugely practical, brilliant to drive and will almost certainly ruin someone’s day on the commute to work...
Where it falls short
Challenging styling, high spec petrols expensive to buy and run, image is too brash for some.
Use the failure ranking as a pre-test checklist or a haggling lever. Treat the headline pass rate as a fleet-wide trend, not a guarantee on any individual car.
If you own an X6 Xdrive30d M Sport Mhev Auto and your last MOT looked nothing like the ranked failures above, that's normal — individual cars vary widely. The ranking shows the patterns testers flag most often across the country.
