Facelifts from April 2006 onwards, but be aware that some of the pre facelift models were registered after April 2006. Too many differences to list but the main ones are different Headlights, front bumper, rear lights and on the 313's a different bonnet. Inside a general tidy up, different knobs, illuminated key lock, a couple of switches moved around, updated satnav from CD to DVD (If fitted), document holder net added, plus a bit more. Rays as Standard. Facelifts are 75 kilos heavier so some other undocumented stuff was added too.
