Inside door handles are different material, steering wheel leather is a different colour, finish on the metal parts of the DSG lever are different old one is brushed aluminium mines chromed, mirror control switch is the older style with heating in the central position (same as MK4 or Leon switch positions) This might just be a perception or treatment over the years but the leather in the older car feels softer and hasnt worn as much as mine. His car also has the diversity aerial gubbins under the driver seat.
