depends if your eligable for good grade discounts or if youve been previously insured on another vechicle, is this your first? I have a 98 Honda civic ex and im about to turn 19 on the 7th, had license since 16 but just got car about a year and a month ago, I live in Indiana and have nationwide, and believe me their quote "nationwide is on your side," is a bunch of BS! I pay 152 a month with no tickets or accidents, so just depends on company and mind you that is just liability... fml, insurance sucks lol, could put so much money into car if you didnt need insurance, so I would just call around and get quotes on insurance for an Si, theyll give you a good estimate.
