Thank you, the official color code is 670H. Interior was originally 1079 leather red with square weave carpeting medium red 6509. We decided to change the colour of leather and carpet.
Eventually carpeting came from KHM, also square weave Haargarn-Boucle (413A tan mottled).
Generally it was worth it, because better is to enjoy the corresponding interior, than to struggle in the original.
Greetings, Dario.
