If anyone is in New Zealand, I highly recomend you to go and check out http://www.boomrock.co.nz
I went there for a day trip with the local dealer and about 15 MB Customers.
The day trip included a ABS/ESP lesson on a private test track with experienced instructors in the comfort of new C-Class, it's a real hands on experience, with lessons on hard braking and turning to avoid obstacles, traction control and the moose test.
Then it was off to more activities which included clay-bird shooting, 4x4 Experience where the property owner took groups to show off the ML350 and what it can do. This involved steep hill climbs and auto hill decents, over the bonnet water splashes, and a demo of the ESP features by way of doing donuts [:D].
the day was capped off with an amazing lunch prepared by a top chef, in a cottage setting, overlooking the sea on a cliff top position. More details ----> http://www.deviantart.com/deviation/9106161/
and lastly, a round of extreme golf was played more detail ----> http://www.deviantart.com/deviation/8959940/
So contrat your nearest New Zealand MB Dealer to check for the trip dates... You will probably find me there again [|)]
