welcome mate!! The aurion is a GREAT car and since i have had it i have had no regrets on buying. i brought an Sx6 and love it! i think the only way to go is the sprotivo range, the body kits just set them off. they have sporty seats, handle really nice and are just a good overall car. the main reason people buy AT-X's over the sportivos is because they dont like the spoiler (i personally really like it) and if u want the lux or the prodigy just get leather in the ZR6 (i think thats avaliable corrct me someone if they dont offer that).
depense really wat you want in a car mate. if u want a luxury cruiser and thats more ur thing get the prodigy but u can always do that in the sportivo and you get the sporty looks and feel as a bonus that would be my pick mate. in white too btw looks really good :o
good luck with ur choice mate ;)
-B.K.S - Everyone would have one if they could only afford it = \
