I will be seriously considering one when time to replace my Forester comes. We have the CX5 diesels here already, and there are two power levels with choice of 6 speed auto or 6 speed manual. They get excellent reviews, though there was a scare about rising oil levels, and the usual worries around DPFs. Compared with the Forester diesel there is a significant bit more power and torque, plus the Forester diesel is manual only still. I have not driven one yet because when I visisted the dealership to have a look they seemed a bit short staffed, but sat in it and I would say the biggest downside for me is that it feels a size smaller than the Forester despite not being much different on paper. The cabin is a coal mine, not helped by no available sunroof (UK market, some others get one, but it's small compared with the Forester's). Smaller window area too, and tinted rear windows - my pet hate - are standard i.e. unavoidable. Also the cargo area is quite a lot smaller. On the plus side, Mazda manage to get the steering wheel central, a trick that seems to elude Subaru.
