So how old exactly are you? 18? or older? There is a big difference between being 18 and a bit older.
Also, do you have an insurance history, (a no-claims bonus or rating?) That will help too.
And forget about putting it in your parents name or being listed as a part time driver, IMPORT INSURANCE DOES NOT WORK LIKE THAT.
If you are listed, even as a part driver, they will base the quote on you driving it the whole time.
To give you some idea, i have an r32 gtst and it cost me:
Age: 21 Rating: 3 (40% ncb) Value: $16500 Cost: $1700
Age: 22 Rating: 2 (50% ncb) Value: $16000 Cost: $1200
Age: 23 Rating: 1 (60% ncb) Value: $15000 Cost: $900
So there you go.
