Should I buy a Cat N or Cat S car?

Buying a Cat N or Cat S car can be a reasonable decision — often at a meaningfully lower price than an equivalent undamaged car — but it depends heavily on the quality of the repair and how well it's documented, not just the category label itself.

What to look for regardless of category:

• Repair documentation — invoices, photos of the repair process, and parts used, ideally from a reputable bodyshop rather than an undocumented DIY repair
• A post-repair inspection or engineer's report, particularly important for Cat S cars, confirming the structural repair meets an acceptable standard
• Consistency between the damage described in the write-off record and the repair carried out — a mismatch is a red flag worth investigating further

Is Cat S damage realistically repairable?

Yes, in many cases — a structural repair carried out by a competent bodyshop, using proper jigs and equipment to restore the frame to its correct dimensions, can return a Cat S car to a genuinely safe condition. The risk isn't that structural repairs are impossible; it's that not every repair is done to that standard, and there's no way to tell the difference just by looking at the car. This is why verification matters more than the category label alone.

How to verify a repair properly:

• Ask for a structural/chassis alignment report, which some inspection services offer specifically for post-repair Cat S vehicles
• Get an independent inspection from someone unconnected to the sale, rather than relying solely on the seller's word
• Check the vehicle's history for consistency — a car that's had a genuinely professional repair usually comes with a paper trail; one that doesn't is worth being more cautious about

On resale value and insurance:

Both categories typically reduce resale value compared to an equivalent car with no write-off history, with Cat S generally affecting value more than Cat N due to the structural element. Insurance can also be more expensive or, in some cases, harder to arrange for a write-off history car, so it's worth getting a quote before committing to buy rather than assuming it'll be straightforward.
