I'm 24 fella and really struggled to insure my 3 door when I bought it in Jan.

Greenlight and Brentacre were the only ones I found that would cover anyone under 25 on a 3 door. Def give greenlight a call, they came in at £892 for me, when brentacre wanted £1600+.

Is it a 2nd car? Mines on a 3k miles policy and garaged in a pretty good postcode, which also helps.
