Thank you very much to all for your response. I bought this car yesterday and found these problem later. Car headlight was broken from inside bonnet, radio security lock, accident category D etc... Previous owner kept this car for 3 years but accident happened before he bought this car. I mean accident happened in 2010 and previous owner bought this car in 2011. I personality think this is mis-sold deal with hidden description which was not mentioned in car advert at all and not even they mentioned verbally. Is there any legal action for this kind of matter? actually £2700 is a lot of money for me. Previous owner is not picking my phone call and messages. Please advise.

Hi, i bought Nissan micra today from a private seller. Seller didn't mentioned us about any car accident history. It was unluckly rainy weather today.. i couldn't check car properly. When i reached home i noticed car radio security code is locked. then i opened bonnet and noticed that front light is broken as well. then i checked HPI online and findout its category 'D' previous. I did mentioned all this to seller but now he is not picking up my phone call. Please help, i will appreciate your advice.. i paid £2700.
