to those sayin no vinyl i gaurantee only the inserts are leather and the rest is vinyl. I've torn down enough seats to know this unless its an older mercedes or bmw there IS vinyl somewhere on the seat. There are exceptions in higher end cars, but for the most part they have vinyl boxing. You can usually tell cause the vinyl wont absorb color and fade/darken/crack like leather in most cases vinyl outlasts.
