Wood grain? help

My 99 E 320 4 Matic Benz has the dark brown wood grain, and recently the front right passenger door side (where the seat controls are) wood grain cracked really bad, I know that they sell many extra wood grain parts and shift knobs but I havent found a place that would have this part, I am too scared to head over to the local Mercedes dealer because they will definately charge me way more than this small wood grain part would cost, does anybody know a place where I can purchase this online?
