I used to drive a Citroen Berlingo and the load space in that was immense. Plus a level loading platform - no lip to negotiate so big cabs on castors used to slide straight in. I once took me, guitarist and drummer, complete with all our respective kit, to a gig.
I now drive a Skoda Yeti that is superior in every way - apart from load space. More than enough for me + 1 guitarist, though.
