We’ve had one for a few years. Fuel consumption is not great but better than others seem to get, our 2.5 diesel gets about 30. Ours is unconverted; it’s great for camping, we have the choice between sleeping upstairs or downstairs if the weather is manky or we just fancy a change. Even if you’re not sleeping upstairs the extra headroom is awesome. It’s toasty and warm because the mid engine keeps the cabin warm long after you’ve stopped somewhere.
We thought about getting it converted properly, but it’s so versatile as it is – we can camp in it, drive about with 8 people in it or use it to lug stuff around (it just fits 8×4′ sheets in, and we’ve had a two seater sofa and a double bed in it). I take it to work when I don’t ride in.
Since 2009 ours has had a new exhaust (our fault, as we reversed into a grass bank… a random garage in Scotland got us a new one in a day, ace!) and had the rear wheel arches redone, as rust is common there.
Plus it was a THIRD of the price of a VW, and we got an expensive one! This was really what swayed us, and we’d do it again without a second thought.
