Maint are about the same provided you look after your turbo.
Make no mistake, if the turbo pops, its going to hurt, but I am a firm believer in that a turbo behaves like its being treated, and on the late models they are pretty sorted.
Other thing is the auto boxes on the high spec diesels take more abuse then standard due to the higher torque.
Service it, remove the swirl flaps, change the gearbox oil, and they are reliable as hell, these cars can die at 130k on the clock or 330k.
Do some reading, I am a turbo/torque junky so perhaps I am a bit biast on this topic, research and decide for yourself, but take one for a test drive.
