Cat N car meaning: write-off categories for dealers

Cat S vs Cat N: which is better?

For a dealer, Cat N is usually the safer stock than Cat S, because the damage did not affect the structure and a repair is easier to verify. The difference shows up in three places:

• Repair quality. A Cat S repair needs jig measurements and correct welding or bonding. A poor structural repair can make a car unsafe in a later crash.
• Buyer acceptance. Many retail buyers reject Cat S outright; Cat N is easier to sell with a full repair file.
• Finance and insurance. Some lenders and insurers apply stricter rules or higher premiums to Cat S.

That said, a well-documented Cat S repair on a simple car can be better stock than a Cat N car with a cheap, undocumented airbag repair. Judge the repair, not only the letter.

How much less is a Cat N car worth?

There is no fixed percentage: the discount depends on the age, model, type of damage and quality of the repair. Motoring publications in the UK note that on older cars the difference may be a few hundred pounds, while on newer cars it can run into thousands. Expect Cat S to sit below Cat N for the same car.

The practical approach is to work back from the clean retail price. Take a 2019–2021 Volkswagen Golf petrol. According to listings tracked by MyCarDealer in Germany in October 2026, the median asking price of 500 comparable cars was €17,980. A dealer pricing a repaired Cat N example would:

1. Start from the clean market price for the exact version, mileage and equipment.
2. Deduct the discount that buyers in his market demand for a declared write-off, ideally from his own sales history.
3. Deduct repair costs, parts, paint, airbag modules and a calibration of driver-assistance sensors if the front end was hit.
4. Deduct a buffer for a longer time in stock, because write-offs sell more slowly.
5. Bid only up to what remains after his target margin.

MyCarDealer shows the clean market price from current listings in your own country and calculates the margin after VAT and costs, so you can add your own write-off discount on top; try it on one car with the free valuation.

Are write-off categories used in other European countries?

No: the A, B, S and N categories are British. Continental Europe has no common write-off marker, and each country flags seriously damaged cars in its own way, if at all.

• Netherlands. A seriously damaged car can be given a WOK status ("wacht op keuren") in the RDW register. It may not be driven until it passes a damage-repair inspection.
• France. The VGE procedure for "véhicule gravement endommagé" suspends the registration until an approved expert certifies the safety-related repairs. Cars declared economically irreparable (VEI) carry a similar flag.
• Germany. Registration documents do not show a write-off category. An insurer's "wirtschaftlicher Totalschaden" means repair costs exceed the car's value, but nothing equivalent to Cat N appears on the papers.

For importers this matters in two directions. A car written off in the UK can arrive on the continent with no visible marker once it is re-registered. And a car repaired under a Dutch or French procedure may be sold abroad with clean-looking documents. A car history check in the country of origin and a paint-thickness measurement are the minimum before buying.

Buying Cat N and Cat S cars as a dealer

Write-offs can be profitable stock if you buy them as damaged cars, not as clean cars with a small discount. Most of them are sold through salvage car auctions or insurer remarketing.

Before bidding, check:

• photos of the damage before repair, if available, and the insurer's assessment;
• airbag, seatbelt pretensioner and sensor history in the diagnostic memory;
• panel gaps, paint thickness and welding marks on structural members;
• the logbook marker and the history report;
• whether your target buyers and their lenders accept the category.

When you sell, disclose the category in writing and keep the repair invoices. In the EU, a consumer who later discovers an undisclosed write-off can usually claim under the legal guarantee on used cars, and the cost of that claim will be far higher than the discount you avoided.

Can a Cat N marker be removed?

No. The category is recorded with the insurer's data and in the UK on the vehicle record, and a repair does not remove it. A dealer who hides or plays down a write-off history risks misrepresentation claims. The honest way to sell a Cat N car is to price it as one and show the repair file.

Frequently asked questions

What does Cat N mean on a car?

Cat N means an insurer wrote the car off after non-structural damage, such as to panels, lights or electrics, because repair was uneconomic. The car can legally return to the road once repaired to a roadworthy condition, but the write-off remains on its history.

What is the difference between Cat S and Cat N?

Cat S cars had structural damage to the chassis or crash structure; Cat N cars had only non-structural damage. Both can be repaired and used again, but Cat S repairs are more complex, and buyers, lenders and insurers usually treat Cat S more cautiously.

Is a Cat N car worth buying?

It can be, if it is priced as a write-off and the repair is well documented. For a dealer, the profit comes from buying at a real damaged-car price, budgeting the repair properly and allowing for a slower sale.

Does Cat N affect insurance?

Some insurers charge more or ask for proof of repair, and a few decline write-offs. Buyers should check before purchase, so dealers should mention the category clearly in the advert.

Are write-off categories used in other European countries?

Not in the same form. The Netherlands uses a WOK flag in the RDW register and France the VGE procedure, while German registration documents show no write-off category. Imported cars therefore need a history check in their country of origin.
