Just an FYI update.
This went to Solicitors I argued with them for about 2 months.
Turns out it costs about £600 to take a case to litigation (court fees and solicitor bill) most of which you can't claim back. As my bill was about a £1,000 (including the 'extras' my insurance put on) it was not echonomically viable for them to take my case. To be fair they gave me ample chance to feign a spinal injury but I didn't take it.
After chatting to the solicitor for about the hundredth time he leveled with me and said I could take it on my own but he had seen lots of these and without witnesses it would just be me and some bird calling each other liars infront of a judge and he/she would likely call it 50/50 to be on the safe side.
End result. NCD was protected so that ok but I have to buy again. Insurance down rated to 3rd party only. AWeekend spent fabricating bumber, Big dent in wing. A cheque for £225.
Lesson learnt. Always call the police at scene, always get a witness, never move the car (let that traffic build up), but mainly, don't have an accident.
