Thanks droptopp, mystery solved! Weird way for Nissan to hide a screw, especially on an outside body surface. A sticker with the paint code. ok....
Been driving my GT-R almost daily for a couple weeks now. A couple of days ago I got the chance to drive on snowy roads for the first time...what a blast!! AWD is the cat's meow!
So anyway, the first owner of the car did not winter drive it. Here is what I did, since taking ownership of the car a few weeks ago:
1) after purchasing, I had it flatbed towed to my shop (I own a small CNC machine shop). Right beside me is a oil rustproofer guy, who is a friend of mine. I put the car on his hoist, and took off all the underbody panels. He then oil sprayed the shit out of it, and then I put all the panels back with new 316 stainless bolts.

2) I made a front license plate holder. The previous owner had his plate velcro'd to the front of the car, and I didn't think that was going to fly when I was, erm, exceeding the speed limit, and tracking the car etc. My front license plate holder uses the OEM threaded hole for the tow hook....I made it a bit too bulky, it's a bit "butch', but it's all 316 stainless / 6061 aluminum, so it will do for now until I can spend a bit more time on it in the summer.

3) I bought front and rear Tux-Mats for the floors...they cover more than the Weatherguard mats and were cheaper. They fit REAL nice, I'm very happy with them. It remains to be seen how well they last. I did put a Weatherguard mat in the trunk, as Tux-Mats don't make one for the trunk, as far as I could tell.
4) I bought 19" x 9.5" (or 8.5"? can't remember, the paperwork is at my shop) flow-formed OPE rims, and Michelin Pilot Alpin PA4 winter tires (285/40 R19's)...that way the outside diameter of the tires is approx the same as stock, and because they're all the same size rims AND tires, I can easily rotate them every winter. The rears are recessed in the wheel wells a bit, but I can live with that...I bought 20mm spacers for the rear wheels, but haven't bothered to install them yet, I may do that still or I may wait until next winter to use them.
And now...I am DRIVING THE SNOT OUTTA IT :-)
