Group 14 car and your age mean you will have your pants pulled down. Most of the specialist insurers won't touch you becaus eof your age/inexperience I'm afraid.
All you can do is phone around and see what you can get, back pages of the car mags is a good place to start. Look at putting your mum/dad on the policy as a named driver as this can bring it down. Don't be tempted to get your mum or dad to insure it with you as thenamed driver as although this is cheap it's aslo insurance fraud which if you are caught out for will have you bending over for the soap come shower time.
