i would say go for chevy's beat witnessed it in auto expo... looks promising...
etios they say it's still in concept phase wud launch it in 2011.... and about polo the price is still not confirmed for the indian market(asked the german guy at 10th auto expo)... also its not the same engine they use it in European markets, but it has a better boot space and a better leg room...... so you will have to wait and watch..
i would recommended chevy's beat seeing the current market if u are planning to buy a car in feb '10....
