saw one with vic euro plates in frenches forest couple of nights ago... i prefer them mechanically to the astra... 5 cylinder is more appealing to me, but i prefer the look of the astra... i suppose it would come down to the cost... if i had to get one of them...
(admittedly i havent really looked at either of them in too much depth, but i think both of them are good for the australian car market)
