I think spec and performance would be similar to the Shogun Sport I had (til it was taken without consent!!!)
That performed realy well on the lanes but did lack any form of diff-lock and suffered with ground clearance issue for play sites.
It did have limited slip diff but I will admit the disco does perform better so far off road on the sites.
My mate at work has one but he owned it in Saudi so only drove it in the desert. Said it was great though, maybe Southport Beach appeals to you :)
Someone posted this te other week, awesome piccies in places
