I run a Landrover Discovery II commercial as my van (in white, of course !). It's big enough (just), very comfortable and great in the snow. Reliability has been fine - just one problem in 18 months so far - and I get about 26 mpg knocking about locally.
Nice flat load bay though the rear door is very big and heavy. Bought it on ebay last year.
Good alarm system and the self-levelling rear suspension means I can carry heavy loads safely without compromising the steering (big problem with estate cars and 20 bags of addy !). It's fairly battered so I'm not too precious about it and so long as I keep away from LR dealers, servicing is not too expensive. £299 for a full service including lubing all the 4x4 gear, an MOT and a few bits and bobs.
Easy to add a few hp to the engine too, if you feel the need.
