Ah okay I thought you were talking about this specific Hyundai from the picture. One with less silly tyres would be more useful I think and better for your purposes than the VW.
I would go for the westfalia, you can still take some easy dirt roads if you have to and the Hyundai will be shit on the paved roads. All depends where you want to use it ofcourse.
