dont really want to have to think about this but ..just wondering what you think my wagon is worth,might have to sell it
 

You're asking a very open ended question. It's like the guy I bought fang off, he asked the same question as have many others before and after. His mates got in his ear and said its rare and worth heaps. He asked $3500 for it and still nobody would suggest its worth. It sold to me for $1000 and I still feel I paid too much.
 
As for your bus, without seeing it in the flesh and providing it has no rust I would suggest around the $2000 mark. Mainly as I know of a mint white wagon that couldn't get $2500. 
 
But then again if 2 people want it bad enough it may fetch more. The VB10 market is a difficult one. 
 
My $0.02 worth. Maybe less.
