hi mate
dunno if this helps
at mo iam 25 --3 yncb-- clean liscence -- 520 fully comp with norwich union inc stereo insurance--rac home start breakdown--2 months euro cover--legal cover--windscreen cover-- best bit is the 200 excess loving it
itll be quite exspensive for an 18 year old might be wrth waiting till you next ncb or even one after that

youll have to weigh it up mate -- how much you want the car to how much itll cost you not just the insuarance but petrol tax (its highest bracket) services , parts etc etc
saying that they are pretty good on petrol
good luck whatever you decide
ps excuse spelling iam knackered
