Costs & verdict
Everyday costs, plus how reliable and safe it is
If you’re interested in buying an X3 M Competition, or indeed any of its rivals, it’s unlikely that you have inexpensive, economical motoring in mind. Still, it actually costs slightly less than the Mercedes-AMG GLC 63S to buy outright, although the Alfa Romeo Stelvio Quadrifoglio is less expensive than either. Even so, a basic X3 M is still around twice the price of a Cupra Ateca.
The X3 M’s equipment levels are a match for rivals’, but a quick stroll down the options list can see the price rapidly escalating. Be prepared, too, for fuel economy that hovers around 25mpg – hardly parsimonious but broadly matching that of direct rivals.
Although the X3 M itself hasn’t been tested, Euro NCAP awarded the regular X3 five stars in safety tests, in which it achieved similar individual test category scores to its rivals. Automatic emergency braking (AEB) is standard, as is traffic sign recognition (this uses a camera to read road signs and display the prevailing speed limit on the dashboard), while lane-keeping assistance is optional.
In the 2019 What Car? Reliability Survey, the X3 finished a disappointing second from bottom in its class, while BMW finished above Alfa Romeo and Mercedes but below Porsche in the overall manufacturer standings. You do get a three-year, unlimited-mileage warranty, though.
