Those with the STI how much do you pay each year or atleast if u want just put down the usual estimate. I like the STI and will keep it stock and probably wont do any modifications other than maybe a catback system and some other small stuff. I was wondering how much it will cost a month or to a year for maintenance(other than oil changes which i can do myself). This car probably wont be driven no more than 250 miles a month . Considering I have a commuter car for long driving and better gas mileage.
