Very happy update. Just got the my ES back from the repairers 'Williams Body Shop Bolton'. I've gone over it with a fine tooth comb and it's an excellent repair. They replaced the bumper, headlight, 3 sensors, headlight washers, washer covers, inner wing fixings and anti-crush arm at a cost of £3,940. So far (touch wood) the AA insurance have handled things brilliantly, providing the hire car side of things goes according to plan l will be a happy customer. Until l get my renewal quote next year.
