Ask Charlie (Owner of Prodrift) if the stickers are removable and if you were interested in buying the car would he remove them ?He only normally buys very very clean s15's and they are BIMTA Certified so it might be worth a look if it ticks all your boxes ?
Here's another dealer selling one, but not Bimta certified and not aero front http://cgi.ebay.co.uk/NISSAN-SILVIA...ryZ18238QQssPageNameZWDVWQQrdZ1QQcmdZViewItem
