Cat S cars have usually suffered some form of damage to their structure. They can be repaired and resold, but this should be disclosed by the seller.

I think you have grounds to demand a refund, as the seller has misrepresented the vehicle by not telling you it has been involved in an accident. I would recommend contacting the seller and politely but firmly telling them the car was not accurately described and you want your money back. If they refuse, tell them you will seek legal advice and report them to Trading Standards. For your legal rights, see: www.honestjohn.co.uk/how-to-reject-a-car-your-cons...s
