Because even if you pay out £1500 to fix it, and £500 for the salvage you are still £2300 up, and so you could afford to devalue the car by £2300 and you are where you started. I'd likely fix that with a bit of hammering and pulling, then just put a bumper + grille on it and drive it around with £3500 in my pocket to spend on sweets and toys.What is there not to understand???
Why should I suffer from a devaluation of the vehicle (it already has the reported accident on it, now it's written off too), no matter how small, and the process of getting it checked just because the garage and insurance tried to con me? I'm already suffering the aftermath of the accident itself and the increased premiums!
