It's hard to tell condition from a photo, but if it is in really good nick and the turbo installation has been done well I would think it's reasonable. They are a fantastic vehicle and for long haul, rough country trips can't be beaten.

As for the gearbox, you hear a lot about which is best (usually the flexibility of 5 ratios vs the added strength of the 4 speed), but I've had a few of these and not had any worries with either box. My current vehicle has the 4 speed and it's fine.

If I was in the market for one and could get to the location, I'd definitely have a look at it.
