In case anyone needs any workshop manuals, I found a site with them online and freely accessible, for some Imprezas between 1993 - 2006. Not sure how complete they are and I'd assume they'd be for the US market but still handy for doing small (and big) jobs on your car.

Also if anyone wants any manuals not on the above site or you'd just like a copy to have for your garage when working on your car, ranging from 1993 - 2008/2009 I have pretty much most of them which I'd be happy to burn to a dvd for you. Just PM me if you'd like a copy.
