If you gave him permission to use the car (called "Permissive Use") you should be covered. Your insurance rates will likely go up.
Nope.
An insurance company declares a vehicle totaled when the cost to fix the vehicle exceeds 70% or more of its market value.
I totaled my Mustang and was able to buy it back from the insurance company. They gave me the Blue-Book value less my $500 deductable. They would not insure it after I repaired it, I had to switch insurance carriers to get coverage.
The insurance company will pay the finance company not you.
The insurance company. They have in theory bought the car or what was left of it.
When a vehicle covered by insurance gets wrecked, the insurance company looks at how much it will cost to repair. If repairing the bike costs more than it is worth, then the insurance company declares it totaled and pays for a replacement.
It would depend on why the car was totaled and who's fault the accident was and what time of insurance do you have PLPD or Full Coverage
Based on your question, I'm guessing that their policyholder simply didn't have enough coverage to pay for all the damage to all the vehicles involved. I would have to know a little bit more about what happened, but you're only realistic action at this point is taking their policyholder to small claims court. However, if you have your own coverage, use it and let your insurance company deal with it.
Totaled vehicles which have been rebuilt generally have a "salvaged vehicle" title, or whatever it's called in your state. Vehicles with a salvaged vehicle title are by definition, not as valuable as the same vehicle with a clean title. If the vehicle is subsequently in another collision, the insurance company will not pay as much since the loss was not as great. Insurance companies only need to pay you for the actual value of the vehicle.
No, the insurance company takes the car and they give you the value of the car,(depending on condition,make,model,year,# of miles).
The insurance company will make you an offer.
Legally, if the company pays you for the totaled vehicle, it belongs to them. You can offer (if they don't) to by the scraps back. This would be deducted from your settlement and you would be paid the difference.
