A practical checklist for assessing a Category S car, including structural repairs, evidence, inspection and value.
A Category S marker means an insurer classified the vehicle as having structural damage. The car may return to the road after repair, but the quality of that repair becomes a central part of the buying decision.
Ask for photographs showing the original damage if they are available. They can help you understand which areas of the structure, suspension or body were involved and what should receive extra attention during inspection.
Request repair invoices and details of who completed the work. Structural alignment, welding quality, corrosion protection, airbags and suspension geometry can all matter depending on the damage.
Consider an independent professional inspection, especially on a higher-value vehicle. A tidy paint finish does not prove that hidden structural work was carried out correctly.
Finally, compare the asking price with equivalent non-recorded cars. A Cat S history can affect future resale and insurance, so the price should make sense for the additional history and uncertainty.
How to assess a recorded insurance write-off
A write-off marker changes the questions you should ask. The category, type of damage, quality of repair and effect on value all matter more than the label alone.
What to check
Identify the recorded category and date.
Ask for photographs, invoices and repair evidence where available.
Inspect repaired areas carefully, especially after structural damage.
Compare the asking price with equivalent vehicles that do not have a write-off history.
Why it matters
Category S means structural damage was recorded, while Category N is non-structural. Neither label tells you by itself whether the current repair quality is good, so the physical vehicle and supporting evidence remain important.
What the data cannot prove
History data can identify a recorded insurance event but cannot inspect the standard of repairs carried out afterwards. That requires physical evidence and, where appropriate, a professional inspection.
