From what I understand, the early sti' were classed as WRX but with the STI upgrades done post production, so may not show up on the like of wiki and the vehicle documents but could still be an STI not too sure about the wiper and arial part though, mines a 1998 STI import and mine has the arial on the rear quarter and has a rear wiper
hope this helps I'm sure someone else will know exactly what the crack is with the early classics
