"You guys must be a bit crazy to do something like this" - that was current Formula One champion and Mercedes AMG Petronas F1 driver, Lewis Hamilton's, first reaction as I explained the GLAadventure.

In less than two weeks after we, ever-so-enthusiastically, started the GLAadventure, the team has already clocked good figures - six international borders crossing Turkey, Bulgaria, Romania, Hungary, Austria and Italy.

We spent the first day getting the war paint as it were put on the cars - the GLAadventure decals.

On a journey, a smartphone/tablet is always one of your best companions - whether it is for entertainment or for useful information.

You know how you think you know it all, and not in an egotistical way either - and yet you don't? That's how we all felt - maybe more so in a combined sense - when we descended on a workshop to take us through the vehicles that will be our companions through the GLA Adventure.
