Yeah start with the simple cheap stuff like, de-badge and bumpstrip, side repeaters. Then move on to the more exspensive stuff like alloys and getting it lowered, the i would get new headlights and rear lights.
Also LOL at the little corsa next to the massive Merc
if you find a mate that is drunk get them to "aquire" you a set of astra side repeaters or corsa c side repeaters. And if you hand them a 13mm spanner get them to aquire you a fiat punto rear wiper aswell.
