nah mate afraid not, i've done numerous re-quotes with them over the last few months on loads of different cars, each time they make a ****ing huuuuuuuge fuss about me ensuring that i'm not changing my alloys from the ones that came with the car. I think its pretty ridiculous as the only two reasons I can see them having for this is 1. stealability but this really isn't anything to do with your age. and 2. for cars that are small (i.e 1.1's and 1.2's or basically cars that young drivers can get insured on and afford etc.) come with small wheels therefore boys being boys they will want to slap 17's on there which will obviously put the speedo out.. Still a pretty shitty reason though!!
As soon as i get my ncb above like 4 im leaving directline!
