having a kit doesnt make it a sport. the tech2 kit, as per my touring , was an option that could be fitted on others . sports had an lsd as standard,close ratio gearbox but the same engine as all other 325i's. an on board computer, different interior and black headlining. i believe the only part you couldnt spec as an option when new on other models was the black headlining . my touring came well speced from factory with tech2 bodykit, leather interior,electric windows,lsd etc. just because it has sport on the log book doesnt mean it is a sport, get the dealer to check the vin to confirm but a decent sport will cost £4000+ whereas a 325i in similar condition with all the options can be had for £1200. its a badge thing.
