for the record, the original Jaguar wood/leather steering wheel is not plastic - it is wood and leather. In a Jaguar, any and every Jaguar, if it looks like wood, it is wood. The gloss finish is a urethane type of finish but underneath that finish, wood/wood veneer. That holds for the wood fillets on the door panels and console/dash area as well. And the grain is different in every car simply because it IS natural wood, not synthetic.
The wood items in Range Rovers are also real wood.

JLR does not play with terms the way other manufacturers do...the "Artico leather" in Mercedes cars, for example...translation (in minuscule print after the asterisk at the bottom of the page): "synthetic leather".
the seating surfaces in a Jaguar are always leather, not vinyl - and depending on the trim level, the entire soft bits of the interior - dash, console, headliner, door panel inserts, the entire seat cover -front, back and sides- is also leather, not vinyl. This was not the case in the X-Type, however. In these cars only the seating surfaces and the headrests were leather.
