91g question

[vizzo]

Ok looking to buy a one year old ds3 diesel.
Just trying to work out the difference between dstyle and dstyle 91g models. I understand that 91g is more eco friendly and has slightly better fuel efficiency on some cycles (motorway I think) but apart from that is there a difference?

all i remember about the 91g its got steel wheels with hub caps. as the 99g has asheras on it thats was 3 year ago though so might av changed since then
