Hello Ananya,
Will recommend :-
- Power Steering
- Power Window (atleast front door power window... If have children with you then ideally take all 4 door power windows)
- Remote Central Lock
- Height Adjustable Seats
- Ofcourse HVAC (heating vents & Air conditioning)
- Front Fog Lights (if in North India or city with dense fogs during winters)
- Gear Lock
- Music System
