I am definitely biased as I have a Jimny but I agree with Heath and coxsy's comments.
One with a solid front axle (SJ, Sami, "Coily" or Jimny).
And EFI would be nice (Vitara or Jimny).
I was lucky that my daily diver was funded into a club toy by an insurance company due to someone else's poor lane changing (cut in and then immediately stopped in Auckland's 1 second following gap).
There are a couple of small down sides to be forewarned about with Jimny's and possibly the Coily Samurai;
- The front diff is a different design to the old SJ & Samurai with a high pinion... on the plus side the steering is behind the axle and more protected but the pinion is different so a C&P swap to get lower ratios is out of the equation at the moment (unlike putting a Vit C&P into a SJ/Sami).
- The front CVs are not really strong enough for hard use (PC Dan can testify to that with his trails experiences)
- The transfer box uses planetary gears and a chain drive and there is only one choice for a lower ratios (Trail Jimny in Greece) BUT

since they are a separate box an earlier model can be fitted (I have just fitted a SJ410K pick up / SJ30 low ratio 3.05:1 to my toy)
On the positive side a lot of the SJ/Sami stuff fits (like a Lock Right for a Sami) and it is a word wide market place (I got some sleeve bolts for a body lift from Bits4Vits in Wales - in 6 days via Royal Mail!).
Also the Prado axle swap is probably a lot easier on a Jimny or Coily than on a SJ/Sami or Vitara.
I suppose it all comes down to what you want to use it for, how much you are prepared to spend and how much you can engineer yourself.
