Thanks everybody !
I didn't expect so many votes
@ Linx, yeah.. displacement and a good map, .. to tel you the truth I'm just starting at mental ray, and I'm still struggling a bit with the shaders..(other than the obvious, metal & car paint) .
I wasn't to happy with the leather, couldn't get it right before it was to late, but for future pics & project, it should be a little better.
Cheers.
