Which one to select. Basic Models of DZIRE or AMAZE or i20

Basic Models Only. DZIRE or AMAZE or i20 ?. Safety and Backseat Boot Space are essential.Petrol is preferred, Diesel is also OK. Sedan is preferred. No fancy things needed. Yearly 4000 to 6000 km usage only. Mileage is not an issue. Not for resale in next 10 years. Smooth drive style with max speed of 105 km/h only. Interested in Etios Platinum G, but booking stopped.
