I recently purchased a Toyota Yaris Cross, but something was missing from it. It was kind of tasteless, hence I purchased valve covers in blue. It was a revelation, just like adding Maggi to soup. The Yaris has become a rarity on Polish bumpy roads, but the caps are always with me - they have never fallen off, as they really fit perfectly. They do not bleach, they still have a beautiful, clear color despite washing the car 3 times a week. I am really happy and this is not irony. Toyota and their designers should take an example from my copy. I highly recommend it.
