A Mini van?

It struck me recently that I could do with a back up classic for those 
times when I'm halfway through replacing my Rotoflex couplings and find 
the lower vertical link bolt seized and end up spending three days over 
the job when all I originally set out to do was adjust the handbrake. 
You've been there too, no doubt.

A tax exempt Mini van would be the perfect cheap to run, practical and 
fun second classic. Except they all seem to have vanished.
So am I too late? Are the few remaining ones all sought after and 
changing hands at hugely inflated prices, or does that start in a year 
or two?
