Thanks iRage, yes as u correctly said, i don't see any other alternative which offers what Sorento offers in the same price bracket.
And for the petrol and diesel vehicle costs, Vanguard , Rav 4, Vitara , x Trail , CRV prices all goes very closely to the Sorento if not more. And with petrol 2.0 and 2.5 L engines, its highly likely to get around 6 -7 kmpl in the city where a diesel would do at least 1 -2 kmpl more in the same conditions.
