They are NOT real leather!!!!! The seats are real leather but the armrest is only (in german: Kunstleder= imitate-leather). But it matches the color pretty well and is not hard plastic.
I have real leather everywhere but custom, made it my selfe. The armrest and side above the armrest are padded: http://www.der-a2.de/vbtest/showthread.php?t=21773
(The yellow shors the original leather imitate.)
