Cat C?

[Flynn]

Cat a and b can't go on the road.

Cat a is normally fire damaged or someone has died in the car in a serious accidentCat b is severe structural damage
(both of these have to be destroyed)
Cat c is normally servers panel damage or light structural damage
Cat d can be as much as a scratch but if it's not economical for the insurance to repair it, they will cat d it.

I don't get that though, say if someone was murdered in a car, they say it has to be destroyed because it has been contaminated with human tissue, but if the car is otherwise fine then why crush it? Seems a waste when they can just replace the seats and carpet.

On the insurance category thing, the whole 'write off' system is a farce. You could have a crash and then have the damage repaired, no one would ever know. It's only if the other driver wants to go through insurance that you have to inform your insurance company of the details.
