My mate was with Adriun Flux and they rinsed him for under 25 premium, optional premiums, etc etc, when he tried to claim. Be sure of what you need to pay if you have a crash or get ya stereo nicked like he did, (dvd 1ks worth)
Anyway, i'm 24 with 5yrs No claim and Direct Line did mine for £540 which was great, was an extra £50-£60 more if i had an S3. that protected NCB too. Norwich union and RAC have been good for the last few years....I was looking to get a 3.0 supra twin turbo a few weeks back but that plan never got off the ground after i checked my insurance, lol. just ot worth paying that much !!!
