maybe he wants to do this before(if) he does the engine swap it can be a cheap mod and get it out of the way now while hes waiting to save money... so why not?
and as far as the comment about $100 more a month and he could have got a wrx..... you dont know his financial situation.... $100 extra month is a lot to a college student with bills plus you have to add in the cost of insurance , gas as you stated and im sure that $100 turns into $200...
i was originally going to get an evo9mr but insurance was over $1000/month so i went with my second option the sti and that was $750/month
