It is worth how much of it can be re-used
How much was the car worth before it was damaged? These are not reasonable questions. How much the car is worth totalled depends on what kind of vehicle it is, how old the vehicle is, how much damage is done, what parts are salvageable, is the engine still good, how many miles are on it, and lots of other factors might come into figuring the value of the damaged vehicle. There is no single number that allows you to say a totalled vehicle is worth $100 or $1000 or $10,000. I hope you understand my meaning and also take it that I'm not being condescending in telling you this.
If the car costs more to repair than its listed value, then it is defined as "totalled."
You can, but totaled means "not worth repairing". You will spend more money repairing a totaled car than you would buying a new one.
The insurance company.
If a car is "totalled" then it means that the cost of repairing the vehicle makes no financial sense to spend money on it so the insurance company give cash for the vehicle.
It depends on your needs. Gap insurance covers the difference between what the car is worth and what you owe on the car. It comes into play if the car is stolen or totalled (damaged to the point that repair would cost more than the car is worth) while the owner is still making payments.
My car is worth around $18,000.
If it costs more to fix it than to replace it
It would depend on the car, what damage it sustains and how much it will cost to fix, compared to how much the car is worth. For example, in the early 90's, brand new Chevy Sprints, still on the dealer's car lot, would be considered totalled if the windshields were broken by vandals. This was because it actually cost more to replace the windshield, than it did to replace the entire car. Note for Britons: 'To total' in the USA means 'to write off' in the UK.
only if the car was damaged to where it was declared totalled. Then you need to get a Salvage title and have the car inspected.
