A real bummer about the crash, its fortunate that no one was injured.
A heads up.... The other guys insurance company will tell you it's only worth $500 and will try to total it as that will be cheaper than the repairs.
6 years ago my 87 Corvette was totaled with relatively minor damage to the right front corner after it was stolen and crashed. They paid off about $7500 as I was able to show comparable cars for sale
in the area that were well over the $4800 they first offered.
Tell them it's value is "Replacement Cost" not some low ball figure pulled out of a used RV price book. The latter are always much lower than what you can buy for.
BTW: Crossed Fingers don't work with insurance companies, be pro-active and start collecting comparable For Sale
ads now and have them ready to show replacement value when his ins co contacts you.
