i used to have the first xtrail (2003). the 250x. the difference would be xtrail is taller inside. whle the XV is car like inside.

road manners. id go with the XV. just because it runs like a car. plus thrifty on the gas. the xv feels planted.

rough roads i would say the same. but the xtrail has a better outward view than the XV. so driving for offroad xtrail.

interior finish. XV wins hands down. my xtrail developed some nasty rattles inside. lalo yung tire cover at the back. had to put lots of sound deadening there. plus interior easily scratches due to the plastic finish. though the aircon vent/drink cooler is a nice touch. xv is nicely built.

but... being the use of the xv or xtrail is more on city roads. xv gets my vote.
