It was the unavailability of a diesel automatic that crossed this car of my list (I got a V70 AWD instead). But, judging from this report it seems that, even if an automatic had been available, it might not have been as good a choice as the V70. I suppose I must wait to see how reliable the V70 turns out to be before I have a definitive answer (trustworthiness means a lot more to me than B road entertainment value).
So far I am very happy with the V70 (the first Volvo I have owned). The D5 engine has great, honest grunt and the car is really, really comfortable on a very long run. This is the first car I have had with an active cruise control and I am amazed how much stress it takes out of inter-city driving. Having said that, the navigation system is hardly state-of-the-art and the autobox has a mind of its own - but not to the extent of being really annoying.
