This doesn't look bad and may just be a residue of many miles on the dipstick.
Grey usually indicates very fine metal particles.
Keep an eye on things and if it doesn't seem to be continuing, relax.
As a couple of those above suggested, one as parody and another seriously, a UOA would tell you if you have some ridiculous level of metal shedding as well as whether you have coolant in the oil.
I'd run this oil some three or four thousand and then drain it. You may then want to sample again, since what you see may be simply the cleaning up of previous owner neglect. This car wasn't sold for scrap value because the POs had taken excellent care of it.
I'd recommend a UOA kit from Polaris.
Also, save yourself some money and run a cheaper complying oil, like a 0W-40 from M1, Valvoline or Castrol.
In this old beast in your climate, I'd also seriously consider a 15W-40 HDEO. It'll take anything this little VW V6 can dish out.
