I've just spent that last few days hunting around for insurance for exactly the same circumstances.
I've just bought a Kangoo van for bike and dog carrying duties and got a bit of a shock on insurance prices.
I ended up with Direct Line who eventually worked out the cheapest, but only because my wife's car and our house insurance is with them.
Still £200 though………….
Fully comp, wife and me to drive, 10k a year, 6 yrs ncd.
Exctly the same price as my Astra VXR was!!!!!!!!!!!!
Wouldn't mind, but it's only a 1.5 diesel :-(
