I have a Kangoo which we easily fit a Beta Rev270 in at the same time as a Rev50 and a 20" trials pushbike, as well as tools, kit bag etc. The Kangoo also has better ground clearence than the Combi and others - a must for some of the off road parking that we endure.
Watch out for the dreaded "Road Tax" man on Vans - once registered commercial they stay that way for life !! and it's a good bit more than you pay on a car.
Cheers - Tolly.
