Like 1] Safety - Air bag should be minimum 4 to 6 2] Ground clearance minimum 170 mm and cant touch ground when sited 4 persons. 3] Mileage at least minimum average ( city and high way ) should be > 22 km / ltr. 4] Build quality should be strong. 5] AC should be strong 6] Touch screen and music should be good and have navigation ( Latest updated ) 7] Look - simple and sobar....no more stylish. 8] Engine - 4 Cylinder When i test drive all sadan cars - Dezire , Amaze , Tigor and Aspire. I have found all features in Aspire Diesel top model. But i am surpirze its selling is verry low as compare to others cars while its better then those cars.
