okay, so i have owned my wrx for about 3 months, and i love it. i had never driven stick before this (i know, huge loser), and now i can't stop racing people on the highway. i've been reading through some discussions about the fuel smell in cold weather, and i am still wondering if the repair is necessary. some people say that they have had theirs with that problem for years, and then others fix it right away. i don't know any secret mechanics, so i would probably be stuck with the *******s at the dealership. so.....my questions are do i need to fix it, and where do i begin??
