1- Wind noise is heard while driving at over 150kms speed.
2- Engine noise is very high at idle when vehicle is started during cold or hot engine temperature. it seems it is from engine valves, is there any one having similar complain!

 

i dont know about engine noise but the engine seems to make the car shack at idle. its very light but u can feel the car shake a lil bit. i donoo if u have felt that. and iv been told by the dealer that lots of 300c owners complain about this problem.
