Hello Paul, sorry about my first suggestion!
Try this company - Young Marmalade (I kid you not!!)
http://www.youngmarmalade.co.uk/young_main.php
They supply new small cars and roll the cost of insurance into the deal.
I have just run a quote on a Corsa 1.2 SXi AC and it quoted a 19 year old insurance at £783.00 for 12 months
Have a look they may be able to help??
