Whether cat b is a abi term or not ELV is a EA term and covered under law. Ive had no experince with having one of my own cars cat b'ed or having any claims for right off's for my own cars either

You will see fewer, if you ever saw any at all, cat b's going back on the road in the uk. Why, The insurance db, miafr thingy is uk only as soon as the car is exported it becomes 'unrecorded' that is the biggest issue at the moment imo as it is totally counter productive to the breaker industry as mostly foreign buyers are buying the breakers for more money then they can possibly be broken for.

Also copart who are the biggest re-seller of breakers and salvage have no due dillegeince or good pratice in place for managment of sale of cat b's, if you look at a company called bluecycle they have, lot better systems and protection in place.
