£450    VW Polo, 1,4l front aixle damaged

I had this car for two years, drives like new. have had an accident at low speed, have run over the traffic island. both arms cracked and pushed backwards, into chasis, drivers airbag deployed. i have tried to claim for this, have been refused, for administrative problem. Car starts and running fine, i have had brand new tyres fited, right before accident, worth 200 pounds.
no visible dammage to bodywork and it need to be seen, before purchase. it can be cheap source for a spare parts.
