Hi. i'd say get an STI. Lots of 17 and 18 year olds own them and the markets are getting bigger, broader, and better meaning that the parts are getting cheaper... hopefully. You just have to remember.... it takes approx $2000 dollars in parts to get a Honda to make 20+ hp. With the same amount... you'd get the STI in the 280+ whp range. Just some food for your thought.
