@Kavvz;
Nope dude, I just said that I am not promoting....
But you can see those real wood panels in luxury cars like Bentley,Rolls-Royce, Cadillac, or may even in some versions of Benz, BMW. They are made with oak/pine woods (some times; tree roots!) and all most all are hand-crafted and therefore each panels are different in texture/colour!!!
There were video demonstration telecasted in National Geographic regarding "Ultimate factory-Bentley", in that video they show how those wooden panels are made!
