I know, i dont think its fair myself, i see loads of people who dont even work getting insurance for 1.6's and such like.
There is a few things you need to do here.
Make yourself less of a risk, you can do this in a few ways:-
Miles per year - Minimal Impact, however if you only do 6k a year put that or less if it's true at that point in time, for normal policies it is an estimate not written in stone.
Fully Comp or Third Party? - It seems that now it is more expensive to go third party as you're more likely to hit someone rather than just park in a ditch, try full comp quotes.
Spread the risk - Add you parents as named drivers on your policy, provided they have no offences or risks associated with them, the insurers look at this as them sharing the car however it does not make any difference if they were not to use it.
Choose a different car - Cars associated with younger drivers have higher risk, strangely you may find cars with a higher engine size are less costly to insure to a certain point. For example, a 2.0 Skoda Octavia.
All of the above is perfectly above board, it will make a massive difference - let us know how you get on!
