Should you buy a Cat S or Cat N car?

Updated 3 October 2026 · 3 min read · by DealerPricing

A Cat S or Cat N car can be a sensible buy if it was repaired properly and the price reflects the write-off. Before paying, confirm the category and damage with a history check, see the repair evidence, have a Cat S car inspected, get an insurance quote and value it against the same car with a clean history.

Stolen, finance, write-off, mileage, keepers and plates. No account needed.

Step by step

  1. Confirm the category and what was damaged

    Do not rely on the advert. A history check shows the write-off category, the date of the loss, the insurer and, where the insurer recorded it, the type and location of damage. A car sold as Cat N that comes back Cat S, or with a second write-off, is a reason to walk away.

  2. Ask to see the repair evidence

    A seller who repaired the car properly can usually show it: the repairer’s invoice, the parts used and photographs of the damage before the repair. For a Cat S car ask specifically what structural work was done. If there is no evidence at all, price the car as if the repair is unknown, or walk away.

  3. Have a Cat S car inspected independently

    Cat S means the structure was damaged, so the quality of the repair matters more than anything else. An independent inspection can check panel gaps, welds, alignment and the airbag system. On a Cat N car, at minimum check that every warning light goes out, the airbag light behaves normally and the electrics all work.

  4. Get an insurance quote with the registration

    Some insurers decline categorised cars or charge more for them, and some finance lenders will not lend on them. Get a real quote on the exact registration, and check with your lender if you are borrowing, before you agree a price.

  5. Price it against a clean equivalent

    Find what the same model, age and mileage sells for with a clean history, then negotiate down from there. Remember the record stays with the car for life, so you will face the same discount, and a smaller pool of buyers, when you sell.

Frequently asked questions

Is a Cat N car safer to buy than a Cat S car?

In principle the risk is lower, because Cat N damage did not affect the structure. In practice the quality of the repair matters more than the letter: a well repaired Cat S car can be sound, and a badly repaired Cat N car can still have faults with airbags, electrics or panels. Judge the car and the evidence, not just the category.

Can I get finance on a Cat S or Cat N car?

Sometimes. Some lenders will not finance a categorised car and others treat it as higher risk. Ask your lender before you commit, and do not assume a dealer’s finance offer will be available on that particular car.

Does a dealer have to tell me a car is Cat S or Cat N?

A dealer must not mislead you about a car’s history and should tell you about a write-off record it knows about, or ought to know about. A private seller must not describe the car inaccurately but does not have to volunteer its history, so asking the question and running a check is down to you.

Will a Cat S or Cat N car always be worth less?

Yes. The record on the insurers’ register stays with the car however well it was repaired and however many times it changes hands, so it will always be worth less than an equivalent car with a clean history and will take longer to sell.

What paperwork comes with a Cat S car?

When an owner keeps a Cat S car after a write-off, the log book goes back to the insurer and a duplicate is applied for, so the car will have a replacement V5C. A Cat N car keeps its existing log book. Neither log book is a substitute for a history check.
