if you can go for an older model thats a fresh import,look for one with no modifications then youre sure it hasnt been thrashed off road, i know as thats what i did in my swb
newer ones that dont have the m40 engine in have had alot of complaints on pajero forum,older ones seems more reliable and less electronics to go wrong.
bear in mind that these imports are similar to shogun but higher spec, but also as in japan etc they dont use salt on the roads so they dont suffer corrosion problems as much as uk cars, wether that be a landy, shogun etc etc
as for veggie oil and seperate tank that could take up space which you need unless you have a decent trailer, also unless it cold in summer you could use upto 70% veggie oil to 30% deisal with no problems, of in winter you have to lower ratio as when cold veggie oil thickens, however people overcome this by adding a litre of white spirit to thin it down.
all i used to do was have a few 25 litres plastic containers fill half with diesal half with veggie oil and shake away before filling tank, never had a problem
like i said earlier though people spend a small fortune on fuel system cleaners, yet in a diesal veggie oil will strip the tank and fuel pipes clean, so after using veggie oil and doing a few hundred miles you will need to replace filter which is only a few quid from milners, then its a once a year job and easy to do.
read on here that parts are easy to source for landrovers and non import 4x4's just have a look on the bay and online theres loads of places to get anything you want for a pajero
back seats come out with a few bolts, some people have a shelf put in so that off road stuff, tools,tow rope etc is under the shelf while you still have a large usable space on top for thing you need to get to fast, some great ideas out there
