Carnet and Someone Else's Bike

[Tathagata]

Hi Folks,

Ive done a fair bit of looking around here and am left with a couple of small questions that I need to ask just to clear this all up for me.

My plan is to get an Austria citizen (friends) to buy a bike for me, register and insure it in thier name. Then give me all the paperwork along with a letter stating that it is thier bike but they are loaning it to me for a period of time.

I am going to be touring southern Europe and it from what I can see, I wont need carnets in any of the countries.

I wonder though, in place of a carnet may I have to pay taxes or something? Will this happen in every country and what approximate cost will I be looking at? Will it be easier to get a carnet?

Also. It seems Romania and Turkey may be my only problem areas. I am Australian and so I think both those countries will give me a visa and bike entry for just a couple of months at the border. Can I expect large costs for these?

Lastly, I can find no information on visa's or carnets for Hungary, Romania, Yugoslavia, Croatia, Andorra, Switzerland and Lichtenstein (please forgive my spelling). I assume they will be similar to the rest of Europe, is that a fair assumption?

Thank you very much for any help you can give.

My main worry is that although they say "carnet not needed" does that mean I can freely enter with this bike (registered by an Austrian citizen) or will I get hit with costs that could be avoided with a carnet?

Thanks
