Enjoy your ride.
Once u are done with the 3M under and wheel well coating, and want to do more to decrease noise levels, change to a silent or low NVH rated tyre like the Yokohama Db series.
If u are into D.I.Y. or can pay someone to do so, then can attempt putting in sufficient sheets of DynaMat inside door linings.
One last suggestion, am pretty sure this base model does not come with the carpet cover inside the boot. Order that immediately from Al Futtaim.
To see what I am talking about, have a look at a fully loaded model or the 3.5 V6's boot. There is a carpet lining on the inside of the boot, which also helps decrease noise levels in car.
I know from 1st hand experience that there will still be some noise coming through window linings!
