Define "go anywhere"
We looked at the Panda and the bigger 500x 4 x 4, which is built on exactly the same platform as the Jeep Renegade, just without the ground clearance, and where impressed. However, the "go anywhere" tag would stop on rutted tracks, slippy wet grass and so on. Not because of the capability, but because of road tyres and ground clearance.
The Dacia Duster 4x4 is probably in contention though. Its a Nissan 4x4 system built on a Renault chassis. More ground clearance, more suitable tyres as standard, cheap to buy and therefore you are more likely to have "fun" in the mud as the repair bills are going to be low.
We also looked at the Suzuki Vitara, which is no longer a "small" vehicle and to tell the truth, it felt far to flimsy to risk taking down a farm track. Not exactly cheap once you start to get the likes of Hill Decent etc.
The Jimny is still basically a Landy (SJ) underneath, and it shows with its offroad capability. At £15k brand new for the top spec, it has to be a contender. However, in the words of the Top Gear Review, "The Suzuki Jimny is a tiny, cheap and rival-free hardcore off-roader. Does what it does quite brilliantly. Does everything else appallingly."
