Also ABS brakes .. the early "S" didn't came with, now if you're lucky you can find the SI on a "SE" version which is basically all the extras that used to came with the vtec model minus the rear speaker between the seats ,, but leather seats are awesome LOL, now IMO a SI with little bolt-ons and a good driver (MT) you can beat vtec models .. with the "S" i'm not sure but all preludes are lovelly and are Preludes!
