+1 on this, I'm not a big believer in 'little, informal chats' with the police, a sure fire way for you to chat yourself into trouble.
If it was my car and I was in that situ I probably couldn't remember who was driving 6 months ago, but that approach could mean dropping Mother se350z in it so maybe not an option.
Best thing you could do is post up your predicament on the Pepipoo forum as that's a dedicated site for points/parking/police.
Hope you get it sorted!
