Got the advance version for 2 weeks already. Sadly the add-on accessories still nowhere to be seen. stupid SA.
Been driving without car mat 

The cars drive quite well, very very light. read here about sound proofing issue, i thought it is not so bad initially but after driving during heavy rain last week, can hear waterfall/river cruise which is very very very bad esp from the back tyres.
This is perodua first sedan, they need to learn from others how to sound proof a sedan car.

Anybody successfully resolve this prob?

yep agreed, i'm not expecting that high la. but i think myvi or even axia do not have this sound. i drove both cars also (not mine). it sound like the rear door is open/window open.
will checkout that fb later.

not sure if the soundproof is still not good enough or the speaker is not good enough due to the position at the bottom.. i feel my old saga 2 speaker at the back of the rear seat produce more clear sound than my bezza which I believe because the sound is going up ? =_=  eg like I can still hear the lyrics better than in bezza .. hmm .. not sure if its just because I didnt volume up enough
