Hi,
Sounds like you are after either a rust free imported bus or one that has already had the work done - are you fussy about LHD or RHD?
Rust free from the US or SA - both Midland Earlybay and Scott Wilson can provide both - for one that's been already restored then you'll need to make sure that it has been done to a high quality or you'll be picking bus coloured filler off the drive in a few years time
Also think about age - the earlier wide five bays are desirable, but later ones come with discs and brake servo's - crossovers seem to be more common but may not be as sough after as that '68 with it's multitude of one year only parts
The type will help narrow down the search - Westfalia's are a popular choice for the interior layout and are
usually more available in LHD from the US/SA/Aus - RHD UK is likely dormobile with their funny layout (though I'm biased
) - tintops look better but nothing nicer than being able to stand up inside the van!
exciting times looking for a new bus - of course you could go for luxury and get a converted deluxe microbus with all it's shiny bits on it
If I was buying again I too would stump up the cash and get one that's already been done (refurbed engine, new interior, bodywork sorted and everything waxed & protected) - they come up on the for sale section but do fetch a premium for the piece of mind and lots of resto photo's
I should add - I knew I wanted a 1971 LHD rust free white westfalia with poptop and it took around 3 months for one to come by so patience is definately worthwhile!
