I reckon half leather would not differ much ( in price that is) since they still have to pick a cloth or to be less rude "THE ORIGINAL CLOTH".....

But you are right to calculate the 1800 euros...same overhere
One advantage I forgot to mention is that aftermarket stuff (like eg the leather) gives me tax benefits...'cause it lowers the price "off-factory"
(the price taken by the dutch tax law)

So my dealer in his brighter moments advised me with a few bits and pieces...
