My damage is limited to drivers door, front wing, side skirt and cracked windscreen. Her Yaris is much worse! Bonnet, wing, headlight, side lights, grille and the nearside wheel has blue paint all over so possible suspension damage.
Think they'll write it off in my experience of damage. Car is probably ok though. However before you get excited about accepting their 159. Mine was destroyed in front of me by a bus doing 50mph with loads of witnesses. So bad it made the papers, you wouldn't want to see the pics. They accepted fault and offered a Golf Plus. It was worth £4000 and I could prove that with other ads. They accepted mine was exceptional but would only give £3300. Huge rows followed but to no avail. (started at £2850). The hire car was charged out at an outrageous £1900 for three weeks! And thats why I think I got so little even though it was no fault claim. Be prepared to go to the small claims court, and a lot of hassle! Mine was 1998 V6 Veloce fully loaded low miles and first in the country. Happened in 2006.
