Glad you guys are ok. Sounds like you may have had what dealers call 'certified' cars with all work being done by the dealer. If so, get that documentation to possibly up the value to the insurance company?
Just a thought
It could well be a used car in exceptional condition. And that certainly can make it be worth more.
But.... It’s not a certified used car as OP as a private seller can’t sell it with a manufacturers warranty like a franchise dealer could.
