Get an app on your phone to take date and time stamped photos as you go. One for reference but mostly if you find something big and need to turn it in to insurance it is easier to prove the damage to an adjuster/ damage appraiser for the insurance co. I used to be one, pain sometimes when you get a claim, sleds in pieces, have no idea what condition the sled looked like over all before tear down if you have to pull a valuation to assess for a total loss. Get photos of the ODOmeter reading, VIN#, all 4 sides, damage area etc like a sales add and then photo the damage as you come across it. If you have all that it will make the process go much faster and easier to settle.
That said, I had a lot of shops that missed stuff on their estimate until I inspected. Everybody wants to focus on just the area of the impact or the obvious damage without checked ski alignment with the track etc, looking for signs of something twisted and then have them tear into it and follow the path of the crash inertia directing the crash energy. Example, impact on the front right, follow the direction all the way through the vehicle as if whatever hit it came out the opposite side. On yours, You center punched something so the crash energy goes all the way straight out the back. Don't look at just the impact area. I'd be looking at ski- alignment, any twist in the tunnel or differences in gap between the mounting to show signs of stress or possibility of something tweaked, seat alignment and how it sits on the tunnel, fits with the tank and plastic, clutch alignment helps look for a busted motor mount, twisted driver or jackshaft, bulkhead etc. How's it run? cooling ok? Any of that stuff seem odd I would probably stop and call insurance since a bulkhead, tunnel etc gets expensive quickly and you want to point that out to an appraiser and have them give the authority for teardown (Save you the time to do it and just have a shop do it and let your insurance pay the tab). I had a few guys that were happy as he L L that I looked at it, and decide, no, tunnel, bulkhead etc, total out the unit without doing a complete teardown. Pay them the settlement, they kept the salvage, pay off their loan and/or buy the parts they needed to fix it or put towards some kick azz aftermarket stuff to upgrade to and did all the labor themselves. I had alot of authority to make that call with my company an higher ups didn't know squat about sleds and they just saw that we didn't get in over our heads on sleds anymore for repairs and everybody was happy.
