It's the blood group
All VW's have green blood,dragon green i'm guessing
Avantegarde is colour coded body trim ,leather handbrake with chrome button,colour coded roof etc ,not a lot of difference than the next model down apart from insurance cost for some reason.
2 litres had agg or aba engine,the 1.6 is better than the 1.8 power wise , auto's are unreliable in all models lol
