May God have mercy on your soul, nothing is harder than selling a WRX Wagon unless you're giving it away
I was able to trade my wagon for a sedan a few months ago because I found a member who needed the extra space, maybe try that out. Alot of STI guys end up getting rid of them because they need something cheaper/more practical. But if you want to mod please please please please please trade it in for an STI if you can afford it, you'll be much happier.
