I bet the seats are leather, but honestly that definition isn't as concrete as it seems. This is because all modern automotive leathers (that I know about) are pigmented or coated leathers except for the Ford F150 King Ranch leather of a couple years ago. What this means is that the leather hide itself isn't dyed but instead a color coating is sprayed over the leather. When you feel the 'leather' what you are actually feeling is the urethane pigment coating (similar to pleather).
