If budget is not a problem. NV200 Auto (petrol) is best, as I heard from few owner friends and the mechanic. Heard the petrol uses the latio engine, more reliable.
The manual diesel model uses the renault sourced one, seems more troublesome, apparently.
Anyway, above models are newer on the road, so expect to cost much more.
On the other hand, Liteace is economical in terms of parts and maintenance. Expect to do a proper complete service after purchase, and it will serve you faithfully.
PS: Forgot to add, I'm into my 3rd liteace, first a petrol which was a drinker, and subsequent ones are diesel models. Reliability never in doubt, but buying used/preowned, always luck dependent, obviously.
