You might want to consider this before you decide

Cat D is the least serious category. It usually means that the vehicle has suffered light damage but the insurance company's decision to repair it is dependent on the cost of the repairs and the value of the vehicle.

If you're buying a Cat D car, there's no guarantee that it hasn't incurred chassis damage. You can find out for sure by investing in a full mechanical inspection at an approved dealership, or by RAC Inspections.

If you buy a Cat D car, make sure your insurance company knows about it, otherwise they might not pay up on any claim.
