It depends on what type of insurance it has, but if it's a standard policy, you're unquestionably gonna be SOL in the event of a total loss. The purpose of insurance is to be made whole and if you paid $84K for it you're not going to be paid $116K for it come a total loss; you're being made whole by getting $84K (subject to depreciation), and that's what you paid a premium for. Like it or not cars are considered to be depreciable assets and that's how standard premiums are calculated. If you want your vehicle insured for either a specific amount and/or insist that it's value has appreciated over sticker/purchase price, you need either an actual cash value (ACV) policy or agreed/stated value policy. Of the two the agreed/stated value policy is the better of the two come total loss time as depreciation is still factored into ACV policies...
I previously had ACV policies on custom motorcycles before but went with a stated value policy on my new Hellcat with Hagerty.
With one motorcycle that was wrecked and totaled it was a total shitshow (I can't remember but I think it was Foremost). Bike had over $70K in it and insured for $50K, declared a total loss and they tried to depreciate the fuck of it and their first offer was under $30K and the comps they used were garbage. I proceeded to bury them with receipts, invoices, etc., etc., etc. and got them to settle for the full $50K. That clearly infuriated them as they doubled the premium on the other custom I was insuring with them the following renewal, which I moved to Progressive and was a third what they wanted for an ACV policy.
Agreed/Stated value policy with Hagerty is just that; the car is a total loss and that's what you get paid, the only hitch is that they agree to what the stated value is, and your estimate of market value is subject to their approval. In this particular case I don't think it'd be a real stretch for them to insure this SS for $130K, and your premium would reflect that...
