Correct me if I'm wrong but I think styria once mentioned a new steering wheel was around $1500. Perhaps over $1000 at least. There's so many good 2nd hand w116 ones out there though I'm not so sure about this early 107 type.
As for the AMG spoiler, impressive feedback for the seller. 2000 plus positives, no negs. but he (or she) should offer the spoiler OS where some serious restorers may lurk. It'd cost about $200 to post that thing to the US I reckon. Not much more for someone wanting the original.
As an adjunct to this thing's rarity, I wonder how many real AMG w116's are there, and therefore how many spare spoilers were created?
