older SWB 4bys

Ahhh the things we do. I am in the process of doing pretty much the exact same thing for the exact same reason. It was a tuff decision but the misses has twisted my arm(again). I'm opting to sell the Hilux for a 92 Sierra. The reason I chose the sierra is their price, capability, economy, and the condition you can get for the money. Also I only need it to be a two person tourer so I turfed the rear seat which gives a reasonable amount of storage space.
Any of the 4bys you mentioned would also be great but watch for rust (around doors, windows, gutters, under carpet etc.)
Good luck with your decision.

Nathan,

Go the Bundera. I had one for 4 years and recently sold it to upgrade to an 80 series. It was fantastic,decent offroad,tough as nails and comfortable on the highway. Coil springs make handling and comfort quite good too.
If you get a 22r petrol slip extractors and increased diameter pipe on to make it breath better.

Only real weak spot i found was rear diffs. I had a couple replacements over the years.

Good Luck

Greg

What is your budget? that will decide what you get.

How serious do you wanna make it for offroad? Coils are easier to modify...

NathaneK,
I was thinking about this today while driving the GU, trying to remember how uncomfortable the shorty MK, was, even with an expensive suspension kit. (just have to remember to load it up with all and the kitchen sink, rides great then). Later model with turbo SD33 and 5 speed is the pick of them. Loved every bit of it other than this. The Bundera was much loathed when new, especially the mid wheel base with FRP top. Would probably be a good buy today if you can find one, just factor in extra for new springs/shocks, you would think it had leaf springs the way it rode. The other one to consider is an early diesel Pajero shorty, would be cheap buy in, good motor and may not have been driven as hard as the others, and should be O.K. with only a new set of shocks.
Something to think about anyway, hope this helps
