hey you should also consider getting a quote for your car after you have added all the modifications you are planning.
i'm 19, green p plates and in sydney. first time getting insurance and have been placed as rating 2 (is this normal?) and paying $1964 for a 98 gt-t full comprehensive. stock for now but with a full bodykit, exhaust, frontmount, 2500K wheels and 2500K system my premium goes to $2300. quite reasonable i must say.
