Anyone finds effective solution in substantially reducing the road and tyre noise of our vios? My vios E's noisy cabin is driving me crazy.

You sure? Have you done it yourself?

Anyone did their air-Cond service outside workshop instead of with toyota SC at 30k service interval? Toyota SC charging very expensive compare to outside but air-Cond warranty will void if service outside. Btw my air-Cond still very cool.
