Hi all - I am new to this, so please forgive any faux pas. I just bought a 2010 Prius lll and had the dealer add leather. My car came back and on the back of each of the front seats, there are two huge visible zippers. I was very taken back and questioned my sales rep on this & was told that it is necessary due to the shape of the new Prius seat.....I have never seen leather seats that look like this - is this true? Anyone else have this experience?
