I'm with extreme on this would love a G.
By far the most capable 4x4 out of the box and really you just don't need to mod em, bar perhaps a lift for bigger tyres, the only thing better also wears a Mercedes badge - a unimog.
3 diff locks as standard, and some even come with the full on Merc leatyer interior etc. Still about as comfortable as a Defender though - these were really built for the German army - but with Merc reliablility and spares back up (you can still buy spares for almost every Merc ever built through the normal dealer network).
My guess is someone will snap it up for the buy it now fairly soon, as G's go thats a steal, someone would pay that for the running gear to build a special.
