A Cat N car can be a real bargain or a car to walk away from, and the category on its own does not tell you which. Cat N means the damage was not structural but cost more to repair than the car was worth at the time. On a car worth two thousand pounds, that can be very little damage indeed.
Buy one when the discount is genuine, the damage is documented, the repair was done by a proper body shop and you plan to keep the car for years. Walk away when the seller cannot say what was damaged, cannot produce invoices, or is only knocking a few hundred pounds off the going rate. Start by reading what the category covers on our Cat N page, then check the registration itself.
Insurers use the ABI salvage code, which replaced Cat C and Cat D in October 2017. Cat N covers vehicles with no structural damage that the insurer decided were not economical to repair. That decision is arithmetic rather than a safety judgement. It weighs the cost of repair, including storage and a courtesy car, against what the vehicle was worth on the morning of the accident. A ten year old hatchback reaches that line quickly.
This is why Cat N is such a mixed bag. The same marker sits on a car with a scuffed bumper and a deployed airbag as on a car that was stolen, stripped and recovered without its interior. The category records the financial outcome. It says nothing about how bad the damage was.
Most people read "non-structural" as "cosmetic". They are not the same thing. Cat N rules out damage to the load bearing structure of the car, and that is all it rules out.
None of that makes a properly repaired Cat N car unsafe. It does mean the question "was it only cosmetic?" needs a specific answer rather than a shrug.
A Cat S car has to be re-registered with the DVLA before it can be taxed and used again, and a fresh V5C is issued. Cat N carries no such requirement. The original logbook stays valid, nothing on the registration document changes, and there is no official paperwork trail confirming the car was ever damaged. The marker still sits permanently on the vehicle's insurance record, so it appears on a check even though the V5C looks entirely normal.
That gap catches out buyers who assume a clean logbook means a clean history. It does not. Check the registration.
Enter the registration and get the key facts before you commit to the car.

An MOT is not a crash repair inspection. It tests defined items on the day and will never tell you whether a repair was done properly, so read the MOT history for what was recorded in the years after the write-off date rather than treating a fresh pass as a clean bill of health. On anything expensive, pay an independent inspector.
Paperwork is what separates a good Cat N car from a gamble.
"I bought it like this and the previous owner did the work" is common and is not automatically a lie, but it means nobody alive can tell you what was done. Price for that or walk.
Anything with driver assistance has a camera behind the windscreen and radar in the bumper or grille. Those need calibrating after a repair, and a cheap body shop may have refitted the parts and calibrated nothing. Ask specifically whether the systems were recalibrated and by whom. While you are looking, check for outstanding safety recalls on GOV.UK, because recalls do not appear on a vehicle history check.
The marker never expires, so every consequence is permanent.
| Points towards buying | Points towards walking |
|---|---|
| A meaningful discount against clean examples of the same model, year and mileage | A small discount that does not compensate for the resale hit |
| Photographs and invoices that match the damage the seller describes | Vague answers, no paperwork and nobody who knows what was repaired |
| A common car with plentiful parts, repaired by a named body shop | A complex or high value car, aluminium panels, extensive driver assistance |
| You intend to keep it for years and run it into the ground | You expect to sell it on within a year or two |
| Even panel gaps, straight steering, insurance quotes already obtained | Any sign the repair was cosmetic work over damage left unrepaired |
Compare the asking price against the same model without a marker before you decide anything, because a discount only counts if you measure it against something. A full write-off check confirms the category and the date it was recorded, and shows whether the car carries other markers such as outstanding finance or a stolen record. If it has passed through several owners since the write-off, our guide to what multiple owners really tell you is worth ten minutes.
Hidden finance and write-offs won't show up on a test drive.
