Which used BMW X5 4x4 should I buy?
It’s tempting to recommend the punchy and refined 30d or 40d six-cylinder X5s, but in reality the four-cylinder 25d is almost as good and cheaper to run. Spec levels are divided between SE and M Sport, both of which are well equipped. SE for example includes metallic paints, front and rear parking sensors, 18-inch alloy wheels and leather seats. Upgrading to M Sport means you get sportier styling, bigger wheels, adaptive sports suspension and electrically adjustable front seats, although the slightly firmer ride counts against it.
If you’re after an X5 with the pace to truly excite then either the M50d or X5 M will easily do the job, with the former somewhat cheaper to run.
