im guessing you dont have the car yet?
whoever your currently insured with will insure you
im 27 and with fbd they wont insure you
the altezza is now in the same group as skylines evo's and scoobies insurence wise
your 21 ish and looking to insure a car that a 30 year old would find hard to insure .
its a bit stupid the way insurance is done in ireland .
dont use online quotes ring the companies and take down all the info they give you . you will get better results from ringing them and chat the girls up that are on the phone if they like the sound of you they will do more for you
