Which used BMW X6 estate should I buy?
The first of the diesels is the 30d. It has six cylinders and feels suitably muscular at low revs, yet is no slouch when pushed hard. As the best blend of price, performance and running costs, it’s the one we’d go for.
However, there are two further diesels should you want even more get-up-and-go. First is the 40d, which is based on the same engine as the 30d but adds more power and torque. That means a quicker sprint time, but also worse official fuel economy.
At the top of the range sits the M50d, which gets the same engine but with a triple-stage turbocharger that brings the sort of performance sports cars owners dream about.
Normally we'd say go for the one with the smallest wheels for a comfortable ride, but there just aren't that many SE models to choose from. At least the popular M Sport version has adaptive suspension with a comfort mode you can make full use of over rutted and bumpy roads.
