I am thinking if this is just because I just came from the toll gate together with the 2 jeepneys and both are accelerating...

Is sound deadener available in the casa? Maybe I can ask them when I have my first 1000KM checkup.
I don't think casas have it, but you can easily find one in any reputable car shops. I suggest though that you observe first for a few more weeks (since it's holiday season :P, you'll have plenty of time). If you still find it unsettling then have it checked in casa since it's brand new, it might just be the weatherstripping or any minor "open holes". Cheers!
