its more to do with value and appeal long term too tbh, impreza's aint worth a wank now, my one could do wth a respray in areas and i have a relative good spec apart from the basic engine, i could reshell into a 3 door shell and increase the value AND due to less being made and lots being broken they will increase invalue ( long term though but it aint going anywhere)

also the 3 doors seem to be better looked after aswell so generally more tidy shells too
