Yes. Cat D's can be written off, for example, because the car was stolen, later found intact, but the insurer had paid off the policyholder before the car was found. Cat C's are written off because the insurer calculates that the cost of repairing the car plus the cost of courtesy car during the repair is greater than the market value minus the salvage value.

If your car is judged to be a Cat C you can usually keep it if you want and only receive market value minus salvage value, then use that money to repair it yourself.
