Just had a look at some pics on the Autotrader website and have to say that the wings do look very similar. The bonnet and bumper is different, as is the grille. The only other external difference between the two marks, other than wheels, as far as I know, is the rear lights. The Mk2s have rather natty looking LEDs in them, although not everyone seems to like them. If you also put leds in the sidelamps, as I have, it will really reduce current draw and reduce the possibility of a flat battery should you inadvertently leave on your lights. Something which I have done a few times in the past!
