Ok now i have few bits to share with you First of all Aveo has best Cabin noise level which is much better then other cars in the segment.
Brakes will get smoother after 1500 Kms approx. During your first check up with dealer tell him about noice on 2000 RPM level it will be rectified also let them know on Cabin noise if you feel it is more as i mentioned
since you have black color you may add on silver lines acc from GM on black it suits a lot and would cost about 1000 Rs i suppose.
Did you put ICE ?
