Good but shakes sideways on highway

Engine Performance, Fuel Economy and Gearbox Pick up leaves much to be desired. My 13 yr old Santro has better pick up. 

Ride Quality & Handling Good but shakes sideways on highway uneven road compared to Swift Dzire which is another car I use and which is much much smoother at high speeds 150-160 km/hr.

Areas of improvement  

(1) AC system is the most useless part. Louvers design is obsolete. Even at extreme in positions you fail to get the air flow at drivers seat and which goes only touching your shoulders at the most. You do not get sufficient air pressure and neither the cooling. I have shown it to the service centre and they say it is working fine as per design (which obviously is poor). I have not recommended this car to any of my friends so far. Again I have to say but my 13 yr old Santro has better AC. 

(2) Music sytem comes without a remote and USB socket both of which are a must nowadays.
