So a couple of weeks ago, I was driving in heavy traffic behind a taxi when he stalled. A short time down the road, going around 5mph whilst we were in first gear, he stalled again - but this time, due to the heavy traffic I was closer to him and our cars had a light bump.
My phone had died so had no way of taking pictures should have listened to dp when told to carry a disposable. Although on close inspection of his car, there was no damage, just the 'hackney carriage' sign on the bumper had come off on one side and so was dangling. We swapped details and I called him later on. He said he would prefer to get it sorted between us and he would get a quote from a garage.
Fast forward to yesterday, he calls me and says "I got the quote - £400 but make me an offer". 
I was gobsmacked and asked him exactly what the damage was an could he send me the pictures he had taken. He said "uhh ohh well the sign and the bumper." And kept saying "well how much can you afford to pay? I don't want you to pay £400 or even £300.... Make me an offer"! I persevered with asking for photos and he said he would try. He pressed me for a figure and so I said "to be honest, I didn't expect anything over £50 because to my mind, the only damage was the pin on one side of the sign" - i'm certain there was no other damage - I made sure I had a good look because I had no phone! damn thing
I then received a message saying "we can sort this out if you pay me £100 compensation". Compensation?! Not for damage but compensation?! 
Now, I know that he hasn't contacted his insurance company (whereas I have on an 'information only' basis) as I know this is a legal requirement. The whole thing is stressing me out as it seems like he has just popped the sign back on (because he surely hasn't been driving around for the last two weeks with it half hanging off.) the reason he decided against the insurance company is because there is nothing to fix and therefore nothing to gain for him. Whereas this way he can almost bribe me. He did not send me any photos.
So lovely mumsnetters, what would you do?
