"Is it safe to buy a Cat S car?"

Cat S cars can be safe if properly repaired by qualified professionals. However, structural damage requires expert repair work. Always verify repair quality and get professional inspection.

"How much cheaper are Cat S cars?"

Cat S cars typically cost 30-50% less than equivalent non-written-off cars. The exact discount depends on the car's age, make, model, and repair quality.

Cat S involves structural damage (frame/chassis), while Cat N involves non-structural damage (cosmetic/electrical). Cat S repairs are more complex and expensive than Cat N.
