I'm considering a 2009 X5 Xdrive 35d, but have had poor experiences with diesel when it comes to warming the interior in the winter. Can anyone with an X6 35d comment on warm up times in the winter? Do you know how the warm up times compare with the petrol engine.

It isn't unusual for the temps here to approach -35C in the depths of winter and I don't want a vehicle that just starts producing heat as I am arriving at my destination.

Thanks,
