In reply to lewismansell:
We have a Kangoo van and the road tax is set at commercial vehicle rates which if far more expensive than if it was the MPV version with back seats and windows. No difference with MoTs, but insurance has to be for a commercial vehicle. In my personal experience (NFU Insurance) this is again far more expensive than for the van derived car version and my NCD wasn't transferable from the car and I had to start from scratch with the van. I did phone up a couple of brokers and both said the same, but it'd be worth checking as I don't know if this is universal.
You need to fit van rated tyres too, rather than car ones, otherwise your insurance may be invalidated in the event of an accident. You're also limited to 50mph on a single carriageway. All van drivers ignore this but I have been stopped and 'spoken to' by a police dog handler (in a Transit Connect van!) for doing 60mph. Reversing has to be on mirrors and turning right at 45 degree junctions can be far more awkward/ dangerous without a passenger's help. Virtually all vans are diesel; little chance of getting a petrol version.
Advantages of driving a van are that you can drive like a total kn0b and the vast majority of other road users won't bat an eyelid as it's what's expected. Street cred ok so long as it isn't a white van.
Kangoos are great and the 1.5 Dci engine pulls like a train in all gears. Berlingos and Partners are very good too but avoid the 1.6Hdi engine at all costs. Astra vans good; great engine and easy to service. Transit Connects have an odd driving position (for me at least) and older ones rust badly. Caddy vans are basically Golfs without windows, which drive really well but if fully loaded the 105bhp diesel engine can struggle a bit. The 140bhp Tdi version is a beast.
Despite all the disadvantages, I wouldn't be without a van as they're just so versatile. Even my wife is a convert and drives ours in preference to the car.
