I have had vans for a long time now, Mainly for work, but great with the bikes too. Good for getting out of the weather, sun or rain. Also sleeping in, but they do get bloody cold. Need to fully line inside.
I have a vito. Just don't touch auto's and petrol versions. Cost me 5500 for a new transmission a few years ago and is stuffed again. For 10-15 you will be looking at older models in the vito.
I have been looking at updating myself and been checking out the Hyundi 2.5 TD. 5 year 160k warranty. Heard good reports about them. Spoke to a courier who has already done 160 000k and besides service never touched a thing. They are in the high twenties second hand . Every bit as good as the vito though in my opinion and a shit load cheaper.
