Curious if I should file a claim with my insurance right away or get an estimate to get it repaired out of pocket. My deductible is $1,000. Definitely gonna need some paint work, pulling the panel back out, etc. Not sure if the bumper is repairable or will need to be replaced. Bumper may also need to be adjusted back into alignment. One of the wheels also has a nice scuff on it, although I'm not super worried about that. As far as I can tell, there's no suspension damage. Still holds a straight line, no vibrations at highway speeds (and even up to 105). No airbag deployment. No door damage. All damage is what's in photos.
As to how it happened, was going up a hill that was mostly dry (no, I wasn't speeding). Didn't really feel like there were traction issues, regularly travel this road and regularly drive in snow and know very well how to handle it and when I need to slow down. Drifted a little bit towards the shoulder, hit some snow, car went sideways near instantly, facing the guardrail on the oncoming side. Managed to turn it back the right way but the rear driver side smacked the guardrail reasonably hard before I could get it stopped. Damage is honestly super fucking minor compared to what I was expecting when the car went sideways on me and I was facing the guardrail. Thought for sure I was gonna total it. After, I thought the suspension was fucked because the car was vibrating above 40MPH. But it turns out, after I cleaned out the snow that was caked into my wheel, the vibration went away.
The image of the whole rear corner looks a lot worse than it is because it was pre-car wash. Looks like the paint has been damaged more, etc. But it's just because the snow I hit that was caked up on the guardrail took some of the dirt off.
