where to buy a bike for touring Europe?
 

I am an Australian with both UK and Australian bike licences. I am flying to Europe mid July and will
have only about 10 days to make it to a rally in Finland.

How difficult would it be for me to buy and insure in say Netherlands or Germany (cuttting miles off
my trip)?

Would I have to return to that country to sell the bike or could I offload it in say Britain?

Which eec country is cheapest to buy a reliable but unfashionable middle weight bike, say 250 - 400 cc?
Anything will do as long as its reliable, no electric start or other mod cons needed
