What Cat A write-off means for you
Cat A is the most serious write-off category: the car is for scrap and must never be repaired and returned to the road. Cat B cars are broken for parts, with the body shell crushed, so they are never back on the road either.
Don't buy one, however cheap it looks. Cat S and Cat N cars are repairable, and a repaired car can be driven legally, but you must tell your insurer. Use the Full Check (£9.99), which shows write-off category, before you commit.
