Dune buggy help? - 4 seat dune buggy blueprints

Hi.i Reviel not at my age, but my father and I are planning to make a dune buggy buggy.I LOVE! However, my father told me that I should know more about them first, if I have questions about a building. (I Mayers Manx DUALSPORT mag)

1: Can you build with somthing next to a VW?
2: If I (with or without VW), a developer can install a different car and FastT? (Porsche, Mercedes ,...)
3: I want a car that is around 170 miles per hour. (230 square kilometers. But I'm not sure, I am an American. We can not very well not work with metrics) VW engine enough.
4: In addition to the engine I can put parts of different cars in it? (Tires, lights, seats)
5: If I can use other parts such as Mercedes, I have a symble luxury Mercedes in front of the car? (ForMore style:))

Any good site recommendations buggy?
