Damith, iv had the sportage 2012 for a year now and have done 7500kms. i get around 7kmpl (petrol,FWD,auto) in average traffic and hardly any colombo running. On outstation runs avg of 10 or so. The ride is a bit firm, but that helps it corner well. If i had to pick a vehicle all over again, id pick the sportage without any hesitation. Only negative is the breaks. They are noisy and are rumored to wear out by the 20k mark.
Well whatever you decide to buy, good luck!!
