Unless there is a different variant, the Delica is a 7 seater...
It's basically an MPV body on a Pajero/Shogun chassis and running gear - so drive and handling are similar.
It's more comfortable as a road car, and much better as an MPV, but not as good in the rough stuff.
Part are also more of an issue, as Delicas were never sold in the UK, so there are more specialist parts than for a Pajero, as this is almost identical to a Shogun.
If you go ahead with a Delica, there are no major recuuring flaws with them, but it's better to look for the 2.8 diesel than the 2.5. It's slightly newer, gives 120+ hp over 80 or so in the 2.5, and has a cam chain instead of a belt.
Hope this helps a bit...
