What do you guys make of this?

Looks like a horn button or something. Twenty-five bucks at the moment. ... No idea what else it could be, but this fella thinks it's a hood emblem.
I don't think so:

Looks to be a nipple style hub car center.

Here's another ad; 944/951 variant with some high-dollar-looking turbo modifications (in Ohio for about $6,500):

... and a 2.4 911 engine in LaSalle, Mich., for those interested in a projekt. Dude says he'll throw in a late-seventies exhaust for a local pickup, but he's not doing too well on selling this little gem (it's not even to $600 yet and the auction closes this afternoon):
