I had a 2.5 Pajero with work years ago and found it very slow, so that leaves either a 3.2 DI-D or a 2.8 TD. The 2.8 is a lot less risky as it's not common rail and parts are far more plentiful. As I'll be using this every day I figure SWB will be handier for parking and easier to reverse a trailer with.
Saw this 98 Shogun 2800 manual on Auto Trader yesterday:





Looks well looked after and I like the colour-coding and wide arches these late models get. This one also has Aircon and a few nice bits.
Will keep ye all updated!
