Person, as near I can tell - there were no vehicles it could have come from, and I doubt it was a meteorite impact. At first I thought something had bounced off my windshield, and the GF didn't see any damage, but I had the chance to squish up close to the glass at the next light and could see the big dent on my side of the hood. :-/
Looked to be about the size of a baseball/softball when it went over after impact but that was kinda quick to get a good look at it.
As annoyed as I am, I have a feeling it landed in the least damaging location it could have - windshield or grill would have been a lot worse, and it'd be a toss-up (no pun intended) whether my car would have cleared a rock that size or taken it to the crank case.
Anyone here have experience with getting their hood fixed for something like this? Would they normally roll it and repaint, or is replacement cheaper? Also the GF is concerned colour of the hood won't match perfectly with the rest of the car. Is there a considerable chance of that for these cars?
Were there any flatbed trucks driving near you? Sometimes, truck drivers are dicks, and don't take enough time to sweep off the chips and pieces that fall off of the skids of whatever they were delivering. They hit a bump, rock flies off..
The paint will never match 100% perfect but a good shop will blend the hood respray with the fenders so you would never notice. You could always try and find a used hood at a wrecker which might be cheaper than body & paint work.
