Latest on this is I've decided not to go ahead with this.
If anyone is interested they may be able to take over if you are quick,it will probably need picking up next week.
I found flights from Stanstead to Gothemburg for £10,then the owner will trailer the bus to Gothemburg himself for about £160 (depending on exchange rate) Then he wants 1500 Euro for the bus,about £1120.I found a ferry company that will go from Gothemburg to Tilbury or Inningham for £250.50 (a 26 hour crossing,includes meal and cabin to sleep)
The bus has apparently good brakes and tyres so should be road worthy.The only problem is the front left (cylinder 4) spark plug thread has been screwed after an engine rebuild.I was going to take a rethreading kit and repair it there.I done a practice one on an old cylinder head and it was easy to cut the new thread being alloy.I have some more pictures if you want me to send some to your email.It sounds like a cheap bus.The owner doesn't want any money in advance,so worst way if it looks like it wn't even get you your money back,you can walk away losing £10 for the flight and the ferry crossing back £250.50.
