Which used BMW X3 4x4 should I buy?
Of the numerous engines available, it’s the 20d that we would recommend for its smooth power delivery, strong torque and good fuel economy. The other engines in the range tend to be quite expensive to buy and aren’t as readily available. However, if you only do short journeys, the 20i petrol might be better to avoid diesel particulate filter (DPF) clogging issues.
Our favourite specification is SE, because it gets you all the equipment you really need. xLine is more of an appearance package and doesn’t offer any meaningful extras for the money, while M Sport has firmer suspension as standard and really needs adaptive dampers to soften the ride on badly maintained roads, and not all examples will have this essential extra fitted.
