I'm a salvage dealer......Shall i rant on?? Cat A is a total loss. Vehicle must be disposed of. Cat B is also a total loss, vehicle can be used for spares only. Cat C is damaged beyond economical repair using new genuine parts, usually structual damage, and can be put back on the road but will require a 'vic' check and re-issue of log book. Cat D, means the vehicle has had minor damage (not structual) and has had a claim through an insurance company. Cat d re-sale loss is around a quarter of market value. Most have been repaired well, but look very closely and find out where the damage was. My car is a cat d, but where else would you get a 94 twin turbo aerotop, 40000 miles, minor scuff on front corner........£3000. And living proof......
