My 22-year-old daughter was second in line at a local roundabout in rush hour traffic. The Mercedes-Benz GLA in front went, but then slammed on his brakes as he saw a car coming from the right on the roundabout. My daughter tapped his car at less than 5mph, she has a slight bend in her front number plate and the Mercedes-Benz has a foot-long horizontal scratch on the plastic plate below the bumper. I spoke to the owner and offered to pay for the replacement part, as well as £200 for the inconvenience, because my daughter only has three years No Claims that she will lose. However, he's claiming whiplash and went to the doctors. He's insisting on putting a formal claim in ‘as the right and proper thing to do’. Is there anything we can do? I have spoken with the claims team of our insurer, Hastings, and they have the full details.
