given as standard s4's go for around the 4k mark at the minute think you may get a shade more. it all depends if the buyer minds that technically bits have been changed. do you still have the big radiator guard frame? weren't the challenge bikes marked in places in indelible pen that they were challenge bikes or was that only if they were raced?
yours does look a nice clean well looked after example. i dont mind the cowl. kind of tricolore-esque.
God it really makes me want some S4 wheels for mine though!
