Any idea what a 09 iShift with ~43000 miles is worth? Apart from this damage its is (was) in very good condition
Really sorry to hear of that Mr Onion. There must be more damage behind the bumper itself, as I can't see how just a bumper would result in a total loss. Insurers these days repair with used parts whenever possible, and a used bumper would be c<£200.
Options for settlement may include buying the car back at salvage rate and using the payout to repair the car. It will have a Cat D marker on it, but that's no big deal with the age of car.
If you go the valuation route, then you need to get evidence of market value ready. This would take form of adverts for similar cars on Autotrader, Ebay or Motors.co.uk etc. I'd start getting those together now, screenshots etc will do, so you have an idea of figures.
@Beachball, the hit and run is terrible. I can never understand people that do that. I think you did the right thing not claiming. These days it's just not worth it unless the damage is substantial or there are other parties involved and you have to report the incident.
