Few questions about the wrx. First off is there much of a weight difference between the wagon and the sedan? leaning towards the sedan but the extra space might come in handy... also i'm in love with reliability. that being said should is it a good idea to look for a 2004ish wrx? Or should i cough up the money for say a 2007 or so? i'm a college student and plan on doing some commuting and i was wondering if the differences in maintenance/gas is a huge difference between the wrx and wrx sti. Thanks for the help really appreciate it! Sorry for being such a newbie.
