Mercedes unveils the Lego Unimog

Stop what you're doing. That's right, stop it, especially that. Stop what you're doing and go and buy the Lego Technic Unimog U400. It's only the biggest Technic model of all time...

The 1:12 scale model measures 38.6cm from bumper to bumper when fully built, using 2,048 pieces and actually works. Like, really works.

It's got a pneumatically operated crane with a working gripper arm, a front winch, optional snowplough, full suspension, differentials, a four-wheel-drive chassis, gear block for extreme ground clearance and a working engine complete with moving pistons.

It'll cost you £154.99, available exclusively from Argos and Lego stores. Go and get one. But before you rush out, answer us this: the Unimog is 60 this year and has sold over 380,000 models to date across the globe - how would you celebrate its anniversary? This is how Merc celebrated it - the Unimog concept.

Which presenter built an actual Lego house? Hint: the Nürburgring isn't his favourite holiday spot...
