is it an sti?
mines a v5 wrx v-limited #539/1000
mine also has 555 blue v-limited seats. ive heard there very rare so im guessing they would only come out in the v-limited..then again some one could have put them in them selves...
you can usually tell if its non sti v-limited coz it will have the sti goodies in it (so ive heard) e.g pink shocks yellow injectors mabye a different afm?
tried looking for my model and it has nothing on there about the v5 v-limited wrx ra, so not sure how accurate this site is http://www.catherineandken.co.uk/sti/wrx.html
