Sad to report that my wife is making me sell our 87 wolfsburg.  She
worries about head-on collisions, shoulder belts for the three kids,
airbags, etc.  Picky picky.  Said dragon lady is willing to get,
instead, a 2000 Eurovan.  So I am investigating.  Poptop Eurovans of
2000 vintage appear to command $20-$30K.  Good heavens.  Too much for
a 7-year-old  van in my humble opinion.  However, I've seen many
non-poptops of same year selling for less than $10K.  There's one for
$9K on ebay right now.  This is the buy-it-now price, even. What is up
with this freaky disparity? Is the poptop really worth $10-20K?

Anyway, here's my question.  Can't I get one of those seemingly budget
2000 Eurovans, cut a hole in the roof, and bolt on a poptop?  Will it
take the Vanagon poptop or is that entirely the wrong shape/size?  I
imagine these are easier to come by than the Eurovan one.  How hard
would it be to get an actual spare Eurovan poptop to install on it?
Or does this f-up the air conditioning completely?  Or something even
more crucial...  Any advice would be much appreciated!  Any experience
actually performing this conversion would be even better!

Thanks as usual for the great advice I'm likely to get.
