Quite.
What group is your Mondeo Fox? And your Xantia?
My car is group 6, I was 18 when I took out the policy, didn't hvae any no claims and only a year's driving experience yet I didn't hvae any problems insuring it. Sure, it cost £1300 but people's definitions of "won't get insured" differ. This wasn't actually a great deal more expensive than had I had my own policy on my Cinquecento. I thin kthe quotes for that were between £1000 and £1200. That was a group 2 car. Basic motoring.
It had central locking and electric windows though
