Hmmm, was soll mir das jetzt sagen

Möchtest Du Deinen H2 so umbauen??

[achim1000]

Ist das die Rally Paris-Dakar, die in Südamerika stattfindet?

Ist das die Rally Paris-Dakar, die in Südamerika stattfindet?

hehe, genau die

Aber da sterben immer zuviele

Ok, sind meistens Motorradfahrer, aber nachher haste noch ne Klage am Hals...

Der Dakar H3 hat aber wenigstens mal nen geilen Sound

[Burns]

Aber ausser der Front hat der nichts mit dem H3 (oder anderen HUMMER-Modellen) gemeinsam...

Fährt auch unter der Kategorie "Buggy".

[Burns]

Ach vergessen: Die Seitenspiegel sind auch vom H3

[achim1000]

Ach vergessen: Die Seitenspiegel sind auch vom H3

Und der Kühlergrill!

[GH3]

Hat das Europamodell nicht auch solche Kotflügelverbreiterungen dran?

[Burns]

So ähnlich - nur eckiger!
