Hi Kieran,

That era of BMW X5 is actually a very reliable machine, the most common faults with it mainly being of the electrical variety – specifically, relating to phone connectivity, the DAB radio and the satnav system, which can operate slowly despite being up to date on software etc. However, this isn’t common and it’s a fine vehicle, with one proviso: you're doing very low mileage to buy a diesel car. Of course, we guess the sDrive25d is less money on the used market than one of the petrol X5s of the same era, but note that ‘s’ in the model badging – the 2.0-litre diesel X5 was not all-wheel drive, it only drove the rear wheels. If you’re buying the X5 because you want traction security in winter, you’re going to have to find an xDrive model.
