Try insuring it in your name with your dad on as a named driver.
I do that anyway for my regular insurance and pay c.£1000, so you can imagine my laughter when the guy at Adrian Flux told me it would be £1500 to park it on a much safer road, covering just 1500 miles a year. Nonsense.
Unfortunately my parents house doesn't have a whole lot of space for another car. So now I have turned my search to renting a house with a garage/drive (don't worry, I was moving out in summer anyway, a garage or drive is now just at the top of my requirements list. The new Scirocco can sit in the street if needs be) lol
