Are all the 3rd row seats in all 100 series LC's with them covered with the same material (i.e. are they all vinyl or all leather)? I ask since it seems like there was only one price option for the 3rd row seat for people who bought new LC's (possibly implying that it didn't matter if you had leather or vinyl in the rest of the car, the 3rd row was always the same) Does anyone know if this is the case?
