Hmm a Vitara good offroad??
Maybe not as good as you'd like, low clearance and small wheels and
independent front suspension don't make for a good offroader, you might
as well buy a Subaru, X-trail, Rav4 etc
as far as I am aware it's only real competition is the Kia Sportage as
it also has a low range
the 6 cyl uses a lot of fuel for the size of the thing also, it runs at
quite high revs so would probably be noisy as well

maybe you should be looking at something a bit larger and in a turbo
diesel, A Pajero/Challenger, Toyota Surf, Jackaroo,
all theses will have similar performance on road as a V6 Vitara and
probably better fuel economy and be much better offroad
